Ugh, top-posting...  Reformatted.

Hmm...  The Makefile looks fine (more or less).  The only possible problem
might be that the "cp" command in the install step strips away the execute
permission from the executable, so that's one thing to check...

Another possibility is that one of the DLLs that mmv needs is
inaccessible.  What does the output of "cygcheck mmv.exe" show?
