Markus, I think that r189951 should have fixed this problem (xf.
http://gcc.gnu.org/viewcvs?view=revision&revision=189951), although I suspect
there will still be a compile time increase from GCC 4.7 to GCC 4.8 because of
the macro expansion tracking stuff. Could you please try a recent trunk GCC 4.8
and report back how compile times look for you now?
