[Python-checkins] CVS: python/dist/src/Include pyport.h,2.32,2.33

Update of /cvsroot/python/python/dist/src/Include
In directory usw-pr-cvs1:/tmp/cvs-serv23991/Include
Modified Files:
	pyport.h 
Log Message:
SF bug [#456252] Python should never stomp on [u]intptr_t.
pyport.h: typedef a new Py_intptr_t type.
 DELICATE ASSUMPTION: That HAVE_UINTPTR_T implies intptr_t is
 available as well as uintptr_t. If that turns out not to be
 true, things must get uglier (C99 wants both, so I think it's
 an assumption we're *likely* to get away with).
thread_nt.h, PyThread_start_new_thread: MS _beginthread is documented
 as returning unsigned long; no idea why uintptr_t was being used.
Others: Always use Py_[u]intptr_t, never [u]intptr_t directly.
