There were some known performance regression issues in GCC-3.0{, .1, .2}
which are addressed in GCC-3.0.3 -- basically, GCC-2.95.x did inlining
at lower level whereas GCC-3.x is trying to inline at a higher level
(which by itself is seen as a win); but then some parameters needed to
be tuned in order to achieve reasonable performance.
