[PATCH 1/2] Fix build on newer glibc.

[Eric Blake]

POSIX allows, but does not require, that <fcntl.h> implicitly
includes <sys/stat.h>.  Until recent glibc, most systems did
this implicit inclusion, and m4 was mistakenly relying on it.

* src/m4.h (includes): Add <sys/stat.h>.
* THANKS: Update.

Wow - it's been a while since I touched m4 (perhaps a good
sign that I'm not finding many bugs in the stable version?)

I've switched over to using 'git send-email' to send these
patch messages; hopefully the new format is easy to understand.

This patch fixes a build issue with newer glibc, so I'll
probably release m4 1.4.15 soon...
