I know, I've read the info page, but it *feels* faster. And I understand that
if I have problems the first thing to do is to re-emerge (with -e if
necessary) with saner CFLAGS, but (surprisingly) I haven't found any yet.
And according to the emerge logs, compilation time isn't increased by more
than ~20% on most packages, so it works for me.
