The meaning of AC_SYS_LARGEFILE has changed to no longer even try
to use wider time_t if available.  So use AC_SYS_YEAR2038 as well.
A more-aggressive change would be to use the next Autoconf’s
AC_SYS_YEAR2038_REQUIRED but at least let’s restore the grep 3.8
behavior.
* NEWS: Mention this.
* bootstrap.conf: Add year2038.

   grep 3.8, in that patterns like \w and \b use ASCII rather than
   Unicode interpretations.
 
+  grep no longer fails on files dated after the year 2038,
+  when running on 32-bit x86 and ARM hosts using glibc 2.34+.
