Subject: Sync with Bison, i.e.:
X-Git-Tag: v4.5.4~239
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f6af3459220570436100ebbb4b1dd65db450c6c1;p=thirdparty%2Fcoreutils.git

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 _.
