For consistency between various macros needing ptrdiff_t.
(Since 2006-07-01, gnulib's stdint module is assuming a ptrdiff_t type.
But since gettext's intl.m4 is providing ptrdiff_t if the system lacks it,
we still don't know for sure whether all systems in use really have ptrdiff_t.)

* m4/vasnprintf.m4 (gl_PREREQ_PRINTF_PARSE): Use same check for
ptrdiff_t as m4/intl.m4.
