I've spent the last few months working on improving OpenBSD m4.
I've committed the final patch a few days ago.
So I am very happy to announce that our m4 is now able to handle a large
enough subset of builtins to substitute for gnu-m4 in autoconf.
I believe this to be of benefit to everybody... Apart from copyright issues,
which autoconf people probably don't really care about (or probably not in
the same direction that we do), this does mean that autoconf is robust enough
to work with two distinct implementations of m4. Since my reimplementation
of patsubst and friends is completely different from gnu-m4, it is less likely
that autoconf will depend on `undocumented features' of gnu-m4 in the
future.
