strptime prototype

glibc has a prototype for strptime in time.h, but needs _GNU_SOURCE to
give it.

        * stime.c: Define _GNU_SOURCE for strptime prototype from glibc.  Use
        HAVE_DECL_STRPTIME for when to give own prototype.

        * configure.in (strptime): Use #define _GNU_SOURCE to get the
        prototype from glibc, use AC_CHECK_DECLS rather than AC_EGREP_HEADER.
