Thanks for the report.  What system was this on, and with what compiler?
 Most likely, it is a bug in your compiler and not in m4.  Can you build
gcc for your platform, and if so, does gcc have the same problem with
compiling that file?

Another thing would be to see if you could narrow down which part of
builtin.c is tripping your compiler bug.  You can try a binary search of
commenting out bodies of various functions and seeing whether the file
will compile (the resulting binary won't run, but right now you're
trying to isolate a compiler bug), to see if a particular function is
the culprit that exceeds your compiler's limits.
