> It sounds like I misunderstood something here. These files are used only by autoconf to generate configure? They are not needed by libtool itself in order to drive the compilation? If so, I agree that it seems better not to check them in, though I think we do need the empty directory in the repository and the tar-ball? Otherwise the reconfiguration process seemed to fail.
That's right. The contents of the required m4 files, including
acinclude.m4, gets copied into aclocal.m4, except it seems than those
which reside in the m4 dir may be included. I hadn't notice the
includes before. Then Autoconf uses aclocal.m4 when to instantiate the
macros from configure.ac into configure. On the other hand, the
build-aux files (compile, config.sub, config.guess, ...) are required.
Note also that when leaving out the other m4 files, it does not make
sense to keep aclocal.m4 in the repository either due to the includes.
