Makefile.maint

[Akim Demaille]

Now Bison and Autoconf are using the same Makefile.am again.

Index: ChangeLog
from  Akim Demaille  <address@hidden>

        * Makefile.maint: Sync with Bison, i.e.:
        (po-check): Scan .l and .y files instead of the
        .c and the .h files that they generate.  This fixes the bug
        reported by Tim Van Holder in:
        <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
        Look for N_ as well as for _.  Try to avoid matching #define for
        N_ and _.
        From Paul Eggert.
