I just done it in 37 minutes on a Sun T5240, using 'make -j 100'. I 
could have probably pushed it a bit harder too, as the machine has 128 
hardware threads. This used C, C++ and Fortran.

This was for the 'gcc-4.4.1-RC-20090715' snapshot, which I'm going to 
test, but I doubt gcc 4.4.0 would be too different.
