Well, command.com doesn't do any globbing, so there's no problem
with double-globbing: things get globbed only once, by cygwin.dll.

There may be some problem with escaping or quoting, though.
Does command.com do anything special with quotes?

Yep, that would be a good idea.

But if zsh was not compiled with cygwin, then you would still need
to do some gnarly quoting to get it right, e.g.

	find . -name '"*.c"' -print
or
	find . -name "'*.c'" -print

You would need two levels of quotes, because one would get stripped
away by zsh, and one by cygwin.dll.
