OK, that might go next time.

I think .gitignore files are different because it's content cannot be duplicated
when they're split, but m4/ repeated some checks.
+ we already started to move configuration into configure.ac before
(AC_CHECK_HEADERS and AC_CHECK_FUNCS).
IMHO it's easier to search/work with single file than in many files with very little
content.

Kind regards,
