bugs in "gcc version cygnus-2.7.2-961023"

Thu Apr 24 06:29:00 GMT 1997

Dear developers,
testing the version of gcc usable for Win32 platforms pointed to in
the subject of the mail I detected the following bugs:
1. at declaration like:
 char * PASCAL function();
 forces gcc to get problems parsing the inside declarated
 macro __attribute__(...).
 Using at the other hand 
 LPSTR PASCAL function() compense the parsing problem.
 I detected the problem compiling Sockets.h:
 at the point:
 char * PASCAL inet_ntoa (struct in_addr in);
 changing this line to:
 /*char **/ LPSTR PASCAL inet_ntoa (struct in_addr in);
 helped.
2. In header Defines.h the macro VER_PLATFORM_WIN32_WINDOWS I 
 missed. Following the declarations from bc5 I wrote:
 #define VER_PLATFORM_WIN32_WINDOWS (1)
 to compense the problem.
3. the declaration: char* tempnam(char*,char*); I missed in 
 using #include <stdio.h>
4. Asking your FAQ nobody answered me to solve the problem of
 of automaticaly invoking the C++ constructor/destructor
 code inside a *.dll. The mingw32 files are able to provide
 the correct startup objects to force the linking process 
 collecting all necessary symbols and call "do_global_ctors"
 and so on. Please correct your startup files.
5. import libraries like libkernel32.a do not include all symbols
 exported by the related DLL at Win95. For example the entry to
 CreateToolhelp32Snapshot is not accessible (others too).
6. Not really a bug but a problem is the different declaration
 of fd_set and related macros in Sockets.h and the clib headers.
 Please think about the possibiliy of using both API4s together.
 Bc54s clib is not unix but it gives me the possibilty to
 mix both API4s. It should be a goal for you to reach the
 same behaviour.
7. At least but also not a bug is my hint to ld4s production of tonns
 of *.o files during the linking process. A simple comparision:
 one of the dll4s I need at windows platforms (*.so, *.sl files
 at unix platforms) is compiled by Borlands C++ 5.0 compiler in
 180 seconds. Gcc needs at all unix platforms we use longer.
 But gcc in your distribution needs 20 minutes at the same 
 machine. (Pentium 166, 64MB, 2GB Quantum). Gcc2.7.2 runs much 
 faster at the same machine under Linux2.0. 
My last message to your e-mail addresses to get basicly infos was
bounced by your DNS MX enty. I hope you will send me a 'receipt'
and some comments to my 'frog'-perspective to your work. Please 
dont angry but I hope my hints can help you to develop a really
good alternative toolset.
Thanks to your work and your attention,
 Andrae
