Please don't cram the entire commit message into the subject line. The
standard for commit messages to keep lines only so long that when you
look at them in "git log" in a 80 column terminal they don't get line
wrapped or truncated.
And what is "lemte-2f/marchtype.c"? Maybe you meant lemote-2f/machtype.c?
