(gl_AC_TYPE_UINT32_T): When determining uint32_t
equivalent, substitute $ac_type for equivalent type rather than
blindly using uint32_t *always* which won't work if uint32_t is not
available. Define _UINT32_T to work around typedef of uint32_t if
<sys/sched.h>, <pthread.h>, or <semaphore.h> used on Solaris
2.5.1.
