stdint_.h vs MacOS X 10.4.6

Problem:

The /usr/include/stdint.h file on MacOS X, apparently needs to be
'fixed' by generation of the GNULIB stdint_.h file into stdint.h, but
includes taken later have a problem in that <sys/types.h> actually
does the #include of <stdint.h> for us. This is bad.

On MacOS X, the stdint.h file is protected using this:

#ifndef _STDINT_H_
#define _STDINT_H_

/* contents elided */

#endif

The configure tests seem to find this sufficient reason to work around
the system stdint.h file:

conftest.c:288: error: negative width in bit-field 'check_UINT8_C'
conftest.c:290: error: negative width in bit-field 'check_UINT16_C'

The first set of errors arise using these lines of <sys/_endian.h>

__BEGIN_DECLS
uint16_t        ntohs(uint16_t);
uint16_t        htons(uint16_t);
uint32_t        ntohl(uint32_t);
uint32_t        htonl(uint32_t);
__END_DECLS

the __BEGIN_DECLS is on line 91.

This patch seems to fix things for MacOS X 10.4.6

Does this seem a reasonable patch to you?

I can provide the full config.log file on request.

There is not sys/inttypes.h file. There is an <inttypes.h> file and
it does #include <stdint.h> as required by C99.
