This is happening, but we would need to make a major leap forward on some 
packages.  We'd need at bare minimum, gcc-4.1 CVS HEAD, glibc CVS HEAD, and 
binutils CVS HEAD just to even get the compiler base built.  considering we're 
still on 3.4.4, I don't see this happening for awhile.

geoman's been working on a gcc-4 userland, and has been finding some solutions 
around some rather annoying bugs, like a librt patch we copied from debian back 
in 2003 that came back and bit us, as well as some studies of a new -msym32 flag 
to replace out o64 hacks in IP22/IP32 kernels.

We also use a patch for gcc-3.4.4 that adds optimization (-march/-mtune) support 
for the R10000 processors that hasn't been ported to gcc-4 or carried upstream. 
  Every attempt I've made to get some gcc-hacker to port it (it's only 12kb), I 
either get no response or a link to the gcc info manual on compiler internals.

Once these are fixed, then there's the fun part of actually testing everything. 
  On two ABIs (o32/n32) as well.  And n32 is kind of stuck in the mud again due 
to an undiscovered pthreads bug that h0rks our glib package, making a userland a 
bit impractical.

Safely stated, I think we're gonna be in linuxthreads-land for a wee bit longer :)


> sparc,

I have this running on my Blade 100, and it seems to work well, even with 
glibc-2.3.5 in portage.  Weeve probably has better info on its support, though.
