From: YiFei Zhu <zhuyifei1...@gmail.com> To quote Eli [1] (I can't explain it better than this):
autotools.eclass runs autoheader without options (and in particular without --force). This will only remake config.h.in if there are actual changes to the content, which in turn means that it will be out of date compared to aclocal.m4 (which we very much expect to have changes). So `make` sees that the header is out of date, and runs autoheader yet again, this time updating the timestamp for `make` purposes. This causes QA warning that "maintainer mode" is detected. autoheader and autoconf added --force option at the same time [2], so no reason only autoconf has that option in the eclass and not autoheader. Like, autoconf, a check on WANT_AUTOCONF != 2.1 is added because the feature was added in autoconf 2.52.
