	(AC_CHECK_MEMBERS): Use single invocation.
	(AC_CHECK_FUNCS): Move into single invocation of
	AC_CHEC_FUNCS_ONCE, don't check for presence of C89 functions.
	* config.h.in: Regenerate.
	* configure: Regenerate.

	* intrinsics/time.c: Include time.h, assume time() is present.
	* intrinsics/time_1.h: Conditionally include sys/time.h,
	unconditionally time.h.
	(gf_cputime): Do division in double, fallback using clock().
	(gf_gettime): Assume time() is present.
	* intrinsics/umask.c: Assume stdlib.h is present.
	* runtime/backtrace.c: Likewise.
