I have been using gcc (since 3.0.1) under Cygwin with no serious errors
for ages now. The code generated is not only correct but much faster
than in 2.95.3 for the same optimization level.

I use gcc 3.1 throughout my system now, building everything I use very
often with it, including the Cygwin dll itself. I have built gcc 3.1
(with 3.0.4), cygwin1.dll, bash, ash, and binutils with 3.1, and they
have given me absolutely no trouble whatsoever (apart from binutils
which is a little picky about optimization, but that is not gcc-3.1
specific, it happens in 2.95.x as well).

If you want to go for 3.1, why wait for a Cygwin package, gcc builds
right OOTB, and only takes about 25 minutes from configure to install.
It can also be installed alongside the existing gcc, so you can use both
for different tasks.

That's good to know, some of what I want to use it for is C++.

But how is it for generating correct code?  Does the machine code
correspond 
accurately to what the source requested?

I suppose I can test myself, but one of the things I'd like to do with
it is 
build processor-optimized glibc's for my Linux systems.  It would be a
drag if 
the code was incorrect.

I have been looking at the C++ compiler only - and it is much
better/stricter with respect to ANSI.

gcc 3.1 is certainly the one I would be looking for.
