Someone reported on the pythonmac list that HAVE_UINTPTR_T wasn't 
defined in pyconfig.h while it should have been defined. I'm looking into 
this and am now wondering whether the configure snipped below is 
correct:

AC_MSG_CHECKING(for uintptr_t support)
have_uintptr_t=no
AC_TRY_COMPILE([], [uintptr_t x; x = (uintptr_t)0;], [
  AC_DEFINE(HAVE_UINTPTR_T, 1, [Define this if you have the type 
uintptr_t.])
  have_uintptr_t=yes
])
AC_MSG_RESULT($have_uintptr_t)
if test "$have_uintptr_t" = yes ; then
AC_CHECK_SIZEOF(uintptr_t, 4)
fi

This seems to check for uintptr_t as a builtin type. Isn't one supposed to 
include <stdint.h> to get this type?

Chaning the AC_TRY_COMPILE line to the line below fixes the issue for me 
on OSX and Linux:

AC_TRY_COMPILE([#include <stdint.h>], [uintptr_t x; x = (uintptr_t)0;], [


BTW. This issue is also present in Python 2.4.

Thanks for the report. fixed in r52086, 52087, 52088.
