That bug should be fixed in GNU m4 1.4.2, available here:

ftp://ftp.gnu.org/gnu/m4/m4-1.4.2.tar.gz

(I write "should be" because I couldn't reproduce the problem on my
Solaris 8 box with m4 1.4.1.  However, the fixes do address all the
reported symptoms.)

GNU m4 1.4 has some very subtle bugs that are much harder to debug:
they cause Autoconf to silently produce incorrect results, and I've
run into this problem several times in practice.  I really cannot
recommend 1.4.
