That's interesting, but fortunately way better than the time configure
takes.
Preprocessing is indeed a nontrivial compiler phase, but especially with
gcc-3, I would not have expected that to make a 50% difference.
It could be that for some reason math emulation is enabled because it's a
cross compiler build, but since the architecture is the same I wouldn't
expect that. Still, my area of gcc expertise isn't in that area, so I
would have to research that :)
Still, 50% is a lot to be explained by mere monstrous include files.
Maybe someone should profile it *g*
