Do you need a feature that is specific to cygwin's make or the cygwin
environment?

If not, could you use the make that comes with MinGW
(http://www.mingw.org/)? If a POSIX-like environment is required,
would MSYS do the trick as well (http://www.mingw.org/msys.shtml)?

Alternatively, could you not simply cross-compile it for Windows on
the Linux system? You said the workstation is dual-boot. If you have
to be in Windows to perform other tasks while building it, perhaps you
could virtualize (not emulate) some Linux system and cross-compile it
that way.

Finally, are you sure the problem even has anything to do with cygwin
and cygwin's make? Perhaps ifc is slower on Windows than Linux for the
sort of thing that you are doing? (In that case using MinGW's make,
with or without MSYS, would probably not help.)
