Message : devel: help in comparing Makefile.in from different commits Now that the generated Makefile.in, configure and aclocal.m4 files are no longer committed in Automake's git repository, a simple "git diff" or "git log" no longer shows if and how a change in Automake results in changes to the Makefile.in files and/or configure script of its own build system. Still, the ability to peek so easily at such differences has proved itself quite useful in the past, often revealing inconsistencies and blunders, and sometimes even bugs; so it would be a pity to lose that altogether. With this change, we add a new maintainer recipe that re-introduces much of that capability, by generating and comparing on the fly the Makefile.in, configure and aclocal.m4 derived from two arbitrary commits of the Automake repository. * Makefile.am (autodiffs, compare-autodiffs): New phony targets.
Makefile.am
## Process this file with automake to create Makefile.in
