Just FYI:
It seems icc7 is not good for LAME compiling, at least for me. With
icc7, LAME slows down about 10% comparing icc6.
And, With icc6 and "-fno-alias" option for the compiler, I got one more
(about 1 or 2%) speed gain. But with icc7, I cannot use "-fno-alias",
because it cause an internal compiler error for many files.
My test is done on my Duron 1GHz, Linux2.4.20, 384MB memory.
I don't have and don't know about the P4 box, but at least for me,
icc7 was not good as I expected...
