I've become accustomed to the habit of patch series with one patch per
email; it's easier to reply (when you lump it all into one email, git's
output puts "-- " after the first patch, so my mailer discards to the
other 6 patches as part of a giant signature), as well as discuss issues
for a single patch.

How can the egrep check ever succeed if the declaration check (which
detects macros) failed?  You can further trim this .m4 file.
