I think this has been answered later in the thread, but the short answer
is - the MinGW make won't recognize the cygwin mount table or symlinks,
so you can't use cygwin paths in a MinGW makefile without resorting to
something like "cygpath".

I briefly thought that this might be a possibility but I've since remembered
cases where people complained about their linux makefiles not working correctly
due to the colon handling in 3.80.  This may have been a side effect of the
ancient patches that I had been carrying forward but I have a feeling that
there are cases where a makefile which runs on linux could not be properly
parsed under cygwin.

I mentioned this here:

No, I didn't detect any trace of "peevedness" at all.  I just hate when
decisions that I make have unintended consequences for other free
software volunteers.
