Paul suggested adding the define 
HAVE_DOS_PATHS to the cygwin build of gnu make:

http://cygwin.com/ml/cygwin/2006-07/msg00882.html


Christopher countered with, 

"There is no advantage using cygwin if you want to use a Makefile which
contains MS-DOS paths. Using MinGW makes perfect sense in that case.
Despite having suggested this repeatedly, it seems some users are still
not clear on this concept."

http://cygwin.com/ml/cygwin/2006-07/msg00886.html


Latter in the thread, Paul said this:

"Regardless, I still wonder whether my idea of building make for a POSIX
environment with Cygwin, but setting HAVE_DOS_PATHS explicitly, would
work."
http://cygwin.com/ml/cygwin/2006-07/msg00910.html


Eli  then replied with this:

"When HAVE_DOS_PATHS is defined, Make tries very hard to treat
backslashes and forward slashes in file names in the same manner.  The
only case I remember where we intentionally do NOT treat backslashes
as forward slashes is in the $wildcard function (and in fact in any
other situation that calls `glob' or `fnmatch').
http://cygwin.com/ml/cygwin/2006-07/msg00938.html


So, it sounds like from the thread Paul suggested 
setting HAVE_DOS_PATHS to true for the cygwin build,
but Christopher does not think that MS-DOS paths have
a place in a cygwin version of make.   

I would be willing to try compiling the upstream make
with HAVE_DOS_PATHS to see if it works for me.  However,
if I report back that it works great, then what?  
Christopher would you change the build for cygwin make
to have this option?
