Why are you using a native build of Make with Cygwin tools?  Doing
that is asking for trouble due to subtle incompatibilities like this
one.  The Cygwin build of Make is a much better candidate for this
kind of job, and it does support DOS/Windows file names with drive
letters.  Can you use that instead?  If not, why not?

I tried this today with a simple Makefile that I ran with Cygwin's make:

$(DIR)/myfile2 : $(DIR)/myfile
    cp $^ $@

$(DIR)/myfile :
    @echo foo > $@

This does not work:
Makefile:3: *** target pattern contains no `%'.  Stop.

Are you sure the cygwin make is meant to deal with Windows paths?
