bug in AC_TYPE_UINT32_T on Solaris 2.5.1

[Bruno Haible]

Hi,

The types uint8_t, uint32_t, defined by autoconf-2.59d
AC_TYPE_UINT32_T etc. collide with the types defined in <pthread.h>
on that platform.

Find attached a test project. On a Solaris 2.5.1 machine:

$ echo $PATH

pthread.h looks like this:

#ifndef _UINT8_T
typedef unsigned char   uint8_t;
#define _UINT8_T
#endif
#ifndef _UINT32_T
typedef unsigned long   uint32_t;
#define _UINT32_T
#endif
#ifndef _UINT64_T
typedef u_longlong_t    uint64_t;
#define _UINT64_T
#endif

Therefore I'd suggest to define _UINT32_T at the same time you define
uint32_t, and similarly for the others. Including <pthread.h> in the
test would probably lead to trouble on some other platforms (think
of _REENTRANT or -lc_r ...).
