Which version of bison?  At any rate, the version of m4/m4.m4 in bison.git
is rather old, and should probably be replaced with the version from
autoconf 2.63 or newer.  The bison version suffers from the problem
that
it only finds the first m4 in PATH, whether or not it is good enough.  The
autoconf version has been improved to search the entire PATH, and validate
that whichever m4 is picked is really up to the task, rather than just
relying on its position in PATH.

Meanwhile, the workaround is simple - simply install GNU m4 earlier in
your PATH, or even add a symlink gm4 that points to your fresh
installation of GNU m4.
