There are quite a few modules having an m4 directory. This is where modules put their additional<BR>
m4 macros (unrelated to libtool). There may be additional behaviours associated with having an m4 directory.<BR>
It's still not clear to me. In any case, the libtool macros are shipped in aclocal.m4. I think the issue was libtool v2 versus 1.5.<BR>
I don't think it's a problem anymore.<BR>
<BR>
The -I m4 should not be added when you have no macros in git. Libtool does not need that to work and it will break<BR>
the build on a fresh repo clone because m4 cannot be found.<BR>
