--- Comment #4 from Eric Gallager <egallager at gcc dot gnu.org> --- (In reply to Ian Lance Taylor from comment #3) > filetype.awk is just an AWK script.

Does the endianness actually matter? Neither the elf nor pecoff cases seem to be duplicated for their opposite endiannesses... Also are the octal escape sequences necessary?
