Those gcc bits are shaved off already, that's why the buildworld finishes so quickly now ... My last result with both clang and gcc seems to be: -------------------------------------------------------------- >>> World build completed on Mon Dec 24 22:55:21 CET 2012 -------------------------------------------------------------- real 350m42.363s user 253m5.477s sys 50m0.024s > WITHOUT_GCC=yes in src.conf is > worthwhile.

So far I didn't consider not building gdb, but I agree that it's not too useful when compiling with clang and am already using gdb751 for debugging anyway. My impression was that the base gdb compiles rather quickly (compared to more recent versions) and that it thus wouldn't matter, but I'll give it a try. Thanks for the suggestion. Fabian
