Changelog for autoconf-el-2.69-67.162.noarch.rpm :

* Mon Aug 06 2018 schwabAATTsuse.de- ac-header-major.patch: port AC_HEADER_MAJOR to glibc 2.25- Use %license for COPYING
* Thu Oct 19 2017 jayvdbAATTgmail.com- Require m4 >= 1.4.16 as the versions provided by other distributions are all rejected by the configure script due to bugs.- Ignore Enhances: on non-SUSE distributions.- Do not package standards.info on non-SUSE distributions as it conflicts with the same file provided by binutils.
* Wed Mar 15 2017 dimstarAATTopensuse.org- Also BuildRequire m4 for autoconf-el: it was wrongly assumed that the two spec files would be in sync (but pre_checkin only syncs the Version: and .changes file).
* Thu Feb 09 2017 dimstarAATTopensuse.org- Explicitly buildrequire m4: there is a plan to remove it from the implicit buildroot configuration (just like autoconf itself is no longer part of a long time already).
