Why aren't you using the m4 pre-built for cygwin?

Oh, you aren't compiling for cygwin.  You're trying to do a
cross-compiler build for mingw.  In which case, this is not a cygwin
question, but a cross-build question related to mingw.

Most likely, this is a situation where no one has ever cross-compiled -
m4 1.4.16 was released before the 64-bit mingw project took off, so
while modern gnulib may be able to cope with this situation, the version
of gnulib used at the time of the m4 release obviously does not.  It's
been ages since I've attempted to do a cross-compile to mingw, but as I
need to release m4 1.4.17 sometime anyways to resolve FTBFS on modern
glibc, I'll try and do that before making a release.
