Sorry but m4 has nothing to do with #include. I don't doubt that you
saw some error that mentioned m4 but it undoubtedly came from a package
which used m4. gcc itself does not use m4 to expand #include. #include
files are expanded by gcc automatically without the help of an external
program like m4.
