Heh, I'm probably not the Dave you're looking for... but anyway:

So... why do you think this is a gmp issue? The message says that mpfr is
the problem. It's possible that the real problem is an incorrect autoconf
check. I'm just unpacking the llvm tarball to see if I can see whether it
really thinks that 2.4.1 is known buggy, or if it's maybe failing because it's
a newer version number than it expects (remember all the fails when texinfo
went from x.9 to x.10 because the regex assumed only one digit after the point?)
Also, I haven't seen anything like this with upstream gcc or 4.3, so if it
is a gcc bug, it's already been fixed. While I'm looking through m4 files,
why not do some googling and see if you can find if this cropped up before on
the gcc list?
cheers,
