best way to prevent a cygwin build?

[Paul Allen Newell]

Dear Cygwin:

I have a network of Fedora machines and WinXP running Cygwin. Most of 
the projects I work on can be compiled/linked/run under both, but there 
are exceptions. As in Maya ...

I am not happy with having to run two separate source trees and would 
like a way (as in "best standard") to add something to any Maya makefile 
which will prevent execution if it is being compiled on Cygwin. The best 
I have been able to come up with is a check under each make directive, 
but that's alot of exceptions where I would think only one would be 
necessary.

I searched the GNU make docs and googled for such, but the best I could 
see were bailout rules under a given make rule directive. I can find out 
whether I need to bail by the test "ifeq (Cygwin, $(shell uname -o))" 
but can't figure out a way to have the makefile ask this question once 
for the entire set of make directives in it.

Any suggestions?

Thanks,
Paul
