Surely this will work. But if you have _one_ makefile used to bootstrap the
building process on _any_ machine (I think that's what Kris wants to do),
you'll have to do something very simple to determine the OS type to prevent
make from complaining about not finding 'uname' or whatever.
I provided a Cygwin build system for FreeType2 (www.freetype.org), which
will build on Windows, DOS, different Unices, from one makefile and I use
OSTYPE to differentiate between Windows/DOS and Cygwin.

On B20, I think, it was cygwin32. If we could rely on it being "cygwin" now
and forever, we have no problems with it.
