 Work in progress. 2 tests fail on x86/win32 because the stack
 checking code in ffi_call_win32 is not yet implemented.
 
 Remove most files from _ctypes/libffi_msvc, only two include files
 stay (updated from _ctypes/libffi/...). Other files are used in the
 cross-platform _ctypes/libffi directory.

 On Windows, ctypes does no longer check the stack before and after
 calling a foreign function.
 This allows to use the unmodified libffi library.

-Status
-======
-
-libffi-2.00 has not been released yet! This is a development snapshot!
-
-libffi-1.20 was released on October 5, 1998. Check the libffi web
-page for updates: <URL:http://sources.redhat.com/libffi/>.
-
-
-What is libffi?
-===============
-
-Compilers for high level languages generate code that follow certain
-conventions. These conventions are necessary, in part, for separate
-compilation to work. One such convention is the "calling
-convention". The "calling convention" is essentially a set of
-assumptions made by the compiler about where function arguments will
-be found on entry to a function. A "calling convention" also specifies
-where the return value for a function is found.
-
-Some programs may not know at the time of compilation what arguments
-are to be passed to a function. For instance, an interpreter may be
-told at run-time about the number and types of arguments used to call
-a given function. Libffi can be used in such programs to provide a
-bridge from the interpreter program to compiled code.
-
-The libffi library provides a portable, high level programming
-interface to various calling conventions. This allows a programmer to
-call any function specified by a call interface description at run
-time. 
-
-Ffi stands for Foreign Function Interface. A foreign function
-interface is the popular name for the interface that allows code
-written in one language to call code written in another language. The
-libffi library really only provides the lowest, machine dependent
-layer of a fully featured foreign function interface. A layer must
-exist above libffi that handles type conversions for values passed
-between the two languages.
-
-
-Supported Platforms and Prerequisites
-=====================================
-
-Libffi has been ported to:
-
-	SunOS 4.1.3 & Solaris 2.x (SPARC-V8, SPARC-V9)
-
-	Irix 5.3 & 6.2 (System V/o32 & n32)
-
-	Intel x86 - Linux (System V ABI)
-
-	Alpha - Linux and OSF/1
-
-	m68k - Linux (System V ABI)
-
-	PowerPC - Linux (System V ABI, Darwin, AIX)
-
-	ARM - Linux (System V ABI)
-
-Libffi has been tested with the egcs 1.0.2 gcc compiler. Chances are
-that other versions will work. Libffi has also been built and tested
-with the SGI compiler tools.
-
-On PowerPC, the tests failed (see the note below).
-
-You must use GNU make to build libffi. SGI's make will not work.
-Sun's probably won't either.
-	
-If you port libffi to another platform, please let me know! I assume
-that some will be easy (x86 NetBSD), and others will be more difficult
-(HP).
-
-
-Installing libffi
-=================
-
-[Note: before actually performing any of these installation steps,
- you may wish to read the "Platform Specific Notes" below.]
-
-First you must configure the distribution for your particular
-system. Go to the directory you wish to build libffi in and run the
-"configure" program found in the root directory of the libffi source
-distribution.
-
-You may want to tell configure where to install the libffi library and
-header files. To do that, use the --prefix configure switch. Libffi
-will install under /usr/local by default. 
-
-If you want to enable extra run-time debugging checks use the the
---enable-debug configure switch. This is useful when your program dies
-mysteriously while using libffi. 
-
-Another useful configure switch is --enable-purify-safety. Using this
-will add some extra code which will suppress certain warnings when you
-are using Purify with libffi. Only use this switch when using 
-Purify, as it will slow down the library.
-
-Configure has many other options. Use "configure --help" to see them all.
-
-Once configure has finished, type "make". Note that you must be using
-GNU make. SGI's make will not work. Sun's probably won't either.
-You can ftp GNU make from prep.ai.mit.edu:/pub/gnu.
-
-To ensure that libffi is working as advertised, type "make test".
-
-To install the library and header files, type "make install".
-
-
-Using libffi
-============
-
-	The Basics
-	----------
-
-Libffi assumes that you have a pointer to the function you wish to
-call and that you know the number and types of arguments to pass it,
-as well as the return type of the function.
-
-The first thing you must do is create an ffi_cif object that matches
-the signature of the function you wish to call. The cif in ffi_cif
-stands for Call InterFace. To prepare a call interface object, use the
-following function:
-
-ffi_status ffi_prep_cif(ffi_cif *cif, ffi_abi abi,
-			unsigned int nargs, 
-			ffi_type *rtype, ffi_type **atypes);
-
-	CIF is a pointer to the call interface object you wish
-		to initialize.
-
-	ABI is an enum that specifies the calling convention 
-		to use for the call. FFI_DEFAULT_ABI defaults
-		to the system's native calling convention. Other
-		ABI's may be used with care. They are system
-		specific.
-
-	NARGS is the number of arguments this function accepts.	
-		libffi does not yet support vararg functions.
-
-	RTYPE is a pointer to an ffi_type structure that represents
-		the return type of the function. Ffi_type objects
-		describe the types of values. libffi provides
-		ffi_type objects for many of the native C types:
-		signed int, unsigned int, signed char, unsigned char,
-		etc. There is also a pointer ffi_type object and
-		a void ffi_type. Use &ffi_type_void for functions that 
-		don't return values.
-
-	ATYPES is a vector of ffi_type pointers. ARGS must be NARGS long.
-		If NARGS is 0, this is ignored.
-
-
-ffi_prep_cif will return a status code that you are responsible 
-for checking. It will be one of the following:
-
-	FFI_OK - All is good.
-
-	FFI_BAD_TYPEDEF - One of the ffi_type objects that ffi_prep_cif
-		came across is bad.
-
-
-Before making the call, the VALUES vector should be initialized 
-with pointers to the appropriate argument values.
-
-To call the the function using the initialized ffi_cif, use the
-ffi_call function:
-
-void ffi_call(ffi_cif *cif, void *fn, void *rvalue, void **avalues);
-
-	CIF is a pointer to the ffi_cif initialized specifically
-		for this function.
-
-	FN is a pointer to the function you want to call.
-
-	RVALUE is a pointer to a chunk of memory that is to hold the
-		result of the function call. Currently, it must be
-		at least one word in size (except for the n32 version
-		under Irix 6.x, which must be a pointer to an 8 byte 
-		aligned value (a long long). It must also be at least 
-		word aligned (depending on the return type, and the
-		system's alignment requirements). If RTYPE is 
-		&ffi_type_void, this is ignored. If RVALUE is NULL, 
-		the return value is discarded.
-
-	AVALUES is a vector of void* that point to the memory locations
-		holding the argument values for a call.
-		If NARGS is 0, this is ignored.
-
-
-If you are expecting a return value from FN it will have been stored
-at RVALUE.
-
-
-
-	An Example
-	----------
-
-Here is a trivial example that calls puts() a few times.
-
- #include <stdio.h>
- #include <ffi.h>
- 
- int main()
- {
- ffi_cif cif;
- ffi_type *args[1];
- void *values[1];
- char *s;
- int rc;
- 
- /* Initialize the argument info vectors */ 
- args[0] = &ffi_type_uint;
- values[0] = &s;
- 
- /* Initialize the cif */
- if (ffi_prep_cif(&cif, FFI_DEFAULT_ABI, 1, 
- 		 &ffi_type_uint, args) == FFI_OK)
- {
- s = "Hello World!";
- ffi_call(&cif, puts, &rc, values);
- /* rc now holds the result of the call to puts */
- 
- /* values holds a pointer to the function's arg, so to 
-	 call puts() again all we need to do is change the 
- value of s */
- s = "This is cool!";
- ffi_call(&cif, puts, &rc, values);
- }
- 
- return 0;
- }
-
-
-
-	Aggregate Types
-	---------------
-
-Although libffi has no special support for unions or bit-fields, it is
-perfectly happy passing structures back and forth. You must first
-describe the structure to libffi by creating a new ffi_type object
-for it. Here is the definition of ffi_type:
-
- typedef struct _ffi_type
- {
- unsigned size;
- short alignment;
- short type;
- struct _ffi_type **elements;
- } ffi_type;
- 
-All structures must have type set to FFI_TYPE_STRUCT. You may set
-size and alignment to 0. These will be calculated and reset to the
-appropriate values by ffi_prep_cif().
-
-elements is a NULL terminated array of pointers to ffi_type objects
-that describe the type of the structure elements. These may, in turn,
-be structure elements.
-
-The following example initializes a ffi_type object representing the
-tm struct from Linux's time.h:
-
-				 struct tm {
-					int tm_sec;
-					int tm_min;
-					int tm_hour;
-					int tm_mday;
-					int tm_mon;
-					int tm_year;
-					int tm_wday;
-					int tm_yday;
-					int tm_isdst;
-					/* Those are for future use. */
-					long int __tm_gmtoff__;
-					__const char *__tm_zone__;
-				 };
-
- {
- ffi_type tm_type;
- ffi_type *tm_type_elements[12];
- int i;
-
- tm_type.size = tm_type.alignment = 0;
- tm_type.elements = &tm_type_elements;
- 
- for (i = 0; i < 9; i++)
- tm_type_elements[i] = &ffi_type_sint;
-
- tm_type_elements[9] = &ffi_type_slong;
- tm_type_elements[10] = &ffi_type_pointer;
- tm_type_elements[11] = NULL;
-
- /* tm_type can now be used to represent tm argument types and
-	 return types for ffi_prep_cif() */
- }
-
-
-
-Platform Specific Notes
-=======================
-
-	Intel x86
-	---------
-
-There are no known problems with the x86 port.
-
-	Sun SPARC - SunOS 4.1.3 & Solaris 2.x
-	-------------------------------------
-
-You must use GNU Make to build libffi on Sun platforms.
-
-	MIPS - Irix 5.3 & 6.x
-	---------------------
-
-Irix 6.2 and better supports three different calling conventions: o32,
-n32 and n64. Currently, libffi only supports both o32 and n32 under
-Irix 6.x, but only o32 under Irix 5.3. Libffi will automatically be
-configured for whichever calling convention it was built for.
-
-By default, the configure script will try to build libffi with the GNU
-development tools. To build libffi with the SGI development tools, set
-the environment variable CC to either "cc -32" or "cc -n32" before
-running configure under Irix 6.x (depending on whether you want an o32
-or n32 library), or just "cc" for Irix 5.3.
-
-With the n32 calling convention, when returning structures smaller
-than 16 bytes, be sure to provide an RVALUE that is 8 byte aligned.
-Here's one way of forcing this:
-
-	double struct_storage[2];
-	my_small_struct *s = (my_small_struct *) struct_storage; 
-	/* Use s for RVALUE */
-
-If you don't do this you are liable to get spurious bus errors. 
-
-"long long" values are not supported yet.
-
-You must use GNU Make to build libffi on SGI platforms.
-
-	ARM - System V ABI
-	------------------
-
-The ARM port was performed on a NetWinder running ARM Linux ELF
-(2.0.31) and gcc 2.8.1.
-
-
-
-	PowerPC System V ABI
-	--------------------
-
-There are two `System V ABI's which libffi implements for PowerPC.
-They differ only in how small structures are returned from functions.
-
-In the FFI_SYSV version, structures that are 8 bytes or smaller are
-returned in registers. This is what GCC does when it is configured
-for solaris, and is what the System V ABI I have (dated September
-1995) says.
-
-In the FFI_GCC_SYSV version, all structures are returned the same way:
-by passing a pointer as the first argument to the function. This is
-what GCC does when it is configured for linux or a generic sysv
-target.
-
-EGCS 1.0.1 (and probably other versions of EGCS/GCC) also has a
-inconsistency with the SysV ABI: When a procedure is called with many
-floating-point arguments, some of them get put on the stack. They are
-all supposed to be stored in double-precision format, even if they are
-only single-precision, but EGCS stores single-precision arguments as
-single-precision anyway. This causes one test to fail (the `many
-arguments' test).
-
-
-What's With The Crazy Comments?
-===============================
-
-You might notice a number of cryptic comments in the code, delimited
-by /*@ and @*/. These are annotations read by the program LCLint, a
-tool for statically checking C programs. You can read all about it at
-<http://larch-www.lcs.mit.edu:8001/larch/lclint/index.html>.

-Andreas Schwab ported libffi to m68k Linux and provided a number of
-bug fixes.
-
-Geoffrey Keating ported libffi to the PowerPC.
-
-Raffaele Sena ported libffi to the ARM.
-
-Jesper Skov and Andrew Haley both did more than their fair share of
-stepping through the code and tracking down bugs.
-
-Thanks also to Tom Tromey for bug fixes and configuration help.
-
-Thanks to Jim Blandy, who provided some useful feedback on the libffi
-interface.

-The purpose is to hack the libffi sources so that they can be compiled
-with MSVC, and to extend them so that they have the features I need
-for ctypes.
-
-I retrieved the libffi sources from the gcc cvs repository on
-2004年01月27日. Then I did 'configure' in a 'build' subdirectory on a x86
-linux system, and copied the files I found useful.
