Oh.
Anytime anyone even mentions the -mno-cygwin flag on the Cygwin mailing 
list, they get sent packing to the MinGW group. At least the MinGW/MSYS 
folks try to provide a method of creating native Win32 executables 
without linking to a 3rd party DLL. For the others: When you build in 
Cygwin, your executable links to the Cygwin DLL. To distribute this 
executable, you have to redistribute the Cygwin DLL, which can't operate 
with other versions of itself. One runs into "DLL hell" with 
distributing a Cygwin-built program. MinGW/MSYS really is an 
*alternative* to building in Cygwin.

Though to be fair, I can understand that it may not be in the interest 
of Redhat to do anything about the Cygwin DLL hell. It doesn't do any 
good to intimate, as above, that MSYS "is really just an older version 
of Cygwin", thereby promoting Cygwin over MinGW/MSYS, when in reality 
there *are* distinct differences, though not obvious. And like all 
engineering, the differences are a matter of tradeoffs, one is not 
better than the other.

And I very much appreciate the fact that there is cooperation on 
maintaining the window/cygwin/mingw port of GCC from both cgf and Danny 
Smith.

You must have not digged deep enough:

Oh, and they also mention Cygwin here too:
<http://www.mingw.org/mingwfaq.shtml#faq-usingwithcygwin>

I don't recall Cygwin mentioning MinGW/MSYS...
