Well, remember the kernel is to a large extent already optimized. So most generic optimizations won't help a whole lot. Still you can always try. Plus it's a great way to shake out hidden bugs in either gcc or the kernel...
Well, it bootstraps with -march=pentium4, and glibc compiles and runs fine with it, so P4 support certainly has improved. Exactly how good is it? If only I had a P4 to tell...
Yes. And if you're brave, you can check it out of cvs (Apple's version). Bottom line is that if you're an OS vendor, you can afford to those sort of things.
Yes and no. In theory it's much better. But you have to take advantage of it in the processor descriptions. To date, there hasn't been too much effort on that front. I think only Hitachi SH has had a significant improvement in codegen so far.

Wrong. More than half of the active developers of gcc are at other companies. IBM, Apple, Codesourcery, and others. Heck, a good number are volunteers too. All the more reason to bash them, I suppose...

Mingw32 is still supported, and probably will be for a long time to come. As is cygwin.
