Subject: * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
X-Git-Tag: AUTOCONF-2.59c~336
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=0961b6fc08f82e5efd82d395f6206b0835e21bca;p=thirdparty%2Fautoconf.git

* man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
(.x.1): Ignore the time stamp in the .TH line when deciding whether
to update the man page.  That way, we don't have to check in new
man pages every month.
