OK, I've seen now --- the line markers are actually in the *middle* of
the output.  That's not going to work...  So it really is
gcc-specific; I can't imagine anything else is doing anything that
weird.

Simply removing the line markers won't work, then.  But from what I'm
seeing, the following probably ought to...

diff --git a/Src/zsh.mdd b/Src/zsh.mdd
