Hi,

here is my formal patch submission.  I am not concerned by portability as
configure will define uintptr_t if not found in inttypes.h or stdint.h
(both in libiberty and gcc.  gdb indeed uses stdint.h from gnulib).

Tested by bootstrapping gcc for c,c++ and fortran on x86_64-darwin,
and by building gdb on x86_64-darwin.

Ok for trunk ?

Tristan.

	* gengtype.c (main): Make uintptr_t a known type.

include/
2012-04-05  Tristan Gingold  <gingold@adacore.com>

	* splay-tree.h: Conditionnaly includes stdint.h and inttypes.h
	(libi_uhostptr_t, libi_shostptr_t): Remove, replaced by uintptr_t.

This is OK.

Thanks.
