This is because the msys shell is specially compiled with a hack that
alters command line arguments that look like filenames into their windows
equivalent, before invoking the child program.  And sometimes this hack
backfires, when a command line argument is translated even though it
shouldn't have been.

That is because cmd.exe does not do this command line mutilation, and the
mingw runtime does not do it either.  [It's also one of the reasons I
personally prefer cygwin over mingw - it is much nicer to have the libc
runtime do the file name mapping rather than the shell, so that all
programs do the mapping the same way without the need for wrapper functions.]

I wouldn't worry about it unless people complain - the idea of using a
cygwin environment to cross-compile to a mingw environment is full of
enough other pitfalls that you don't need to bend over backwards to make
it easy - anyone capable of actually pulling it off should also be smart
enough to recognize the limits inherent in such a setup.
