   No. I strongly doubt Apple will ever ship a gcc > 4.2.1 due to a combination
of their objections to GPLv3 and their preception that gcc has been treading
water in terms of improvements. As the FSF gcc developers are fond of saying,
it's hard to make the elephant dance so Apple wanted to start with a more
modern code base and design with clang/llvm. FYI, I maintain the gcc packages for
fink and so far we have had pretty good luck with FSF gcc maintaining quality...

although there will be forks coming like with LTO. Apple wants to use a
different approach for implementing LTO than FSF gcc does. I was told by
the llvm folks...

I am unclear if the FSF design could be adapted for darwin without Apple's
participation on the linker side.
