Actually, Microsoft always has, just likes to hide the fact in case
it's forced to practice the same! If you look at its own now-obsolete
POSIX kit, it included quite a bit of GNU code, including a port of 
gcc. That whole POSIX subsystem and kit is now obsoleted by Interix's 
product.

As for Interix, here's a bit of history: Softway/Interix a few years 
ago started out with Cygwin b17 as the base and built a version of gcc 
and binutils for their POSIX subsystem. GCC didn't need too much 
modification, at least at the basic level, but binutils is a whole 
different story.

Even though Interix now uses newer gcc, their stable codebase still
uses some old code, and that's why you see the cygnus-2.7.2-970404.

I assume the "assimilation" of Interix by MS will have caused some
temporary glitches, but Interix has always maintained full sources
on their ftp site; a bit buried, but the pointer is on their CD and
in docs.

For the record, I have no affiliation with Interix other than some 
productive collaborative efforts with Donn Terry in porting egcs 
to Interix.

Make that *six*; a brand new one -- ix86-pc-win32-gnu -- which uses 
GNU C Library as the runtime. I'm still cleaning out bits and pieces
at this point, mostly in the runtime.

Sorry about getting rather off-topic here ...
