I just tried it, and it compiled without complaints.

Here is a comparison from a PIII 500mhz, gcc 3.2.2 on RH9.


make profile (substituting linux-profile/linux for linux-icc-profile/linux-icc:
......
Total nodes: 72361168
Raw nodes per second: 177355
Total elapsed time: 408
SMP time-to-ply measurement: 1.568627


make linux:
......
Total nodes: 72361168
Raw nodes per second: 150439
Total elapsed time: 481
SMP time-to-ply measurement: 1.330561
