Subject: [PATCH] Port AC_SYS_LARGEFILE to C++
MIME-Version: 1.0

Problem reported by Zack Weinberg
<https://savannah.gnu.org/support/?110983>.
* lib/autoconf/specific.m4 (_AC_SYS_YEAR2038_PROBE)
(_AC_SYS_LARGEFILE_PROBE):
In chatter, say it’s a CPPFLAGS option, not a CC option.
(_AC_SYS_LARGEFILE_OPTIONS): Omit -n32, as we no longer
need to worry about IRIX.
(_AC_SYS_LARGEFILE_PROBE): Fiddle with CPPFLAGS, not CC,
and don’t worry about -n32.
