[PATCH 0/2] Improve m4 memory usage

[Eric Blake]

It's been a long time since I've had any chance to work on m4, and it
shows - it took me way to long to even bootstrap my build again before
I could investigate why m4 was running out of memory on a particularly
hairy m4 program that I wrote for fun
(https://adventofcode.com/2017/day/5 if you must know).

I'm also aware of failures to build with newer glibc, but will need to
patch that separately once I get on a rawhide machine that reproduces
the problem.  Ater that, it's long past due for a maintenance release.
