* m4/stdint.m4 (gl_STDINT_H): Check for inttypes.h and sys/types.h
instead of assuming that AC_INCLUDES_DEFAULT does it.
The old code relied on AC_INCLUDES_DEFAULT being called
and setting ac_cv_header_inttypes_h and ac_cv_header_sys_types_h,
but this does not occur in Autoconf 2.70.

pid_t.m4: just use 2.70
* m4/pid_t.m4 (AC_TYPE_PID_T):
Use Autoconf 2.70 as a prerequisite, not 2.69c.
