I disagree with both of you.

I use Cygwin tools, including Gnu make, to build an ocean model. This 
system supports both Cygwin (g95-cygwin) and non-Cygwin (Compaq, 
g95-mingw) Fortran compilers. (These days I use g95-cygwin mostly, but 
there are good reasons to support the others.)

I don't use Mingw make because the build system was developed on Unix 
and I just don't want the grief of porting it to a naked Windows system. 
BUT I wasn't bitten by the removal of Windows mode in make, because I 
always run make in Unix mode. Make doesn't generally see the Windows 
paths. When I need to pass Windows path to the non-Cygwin compilers, I 
create them on the fly with cygpath. This does require a little care 
with quoting, but I've managed to sort out all the problems I've 
encountered.

I won't go into more detail, but I have posted examples of this in the 
past on this list.
