Hello,

This patch adds to gcc's system.h file the include of stdint.h file,
if present. It uses AC_TYPE_INTPTR_T and AC_TYPE_UINTPTR_T feature of
libtool.

ChangeLog

2009-09-03  Kai Tietz  <kai.tietz@onevision.com>

        * config.in (HAVE_STDINT_H): New.
        (HAVE_UINTPTR_T): New.
        (HAVE_INTPTR_T): New.
        (uintptr_t): New.
        (uintptr_t): New.
        * configure.ac (AC_CHECK_HEADERS): Add stdint.h.
        (AC_TYPE_INTPTR_T): New
        (AC_TYPE_UINTPTR_T): New.
        * configure: Regenerated.
        * system.h: Include stdint.h, if present.

Tested for x86_64-pc-linux, i686-w64-mingw32, and for
x86_64-w64-mingw32. Ok for apply to trunk?

Cheers,
Kai
