output of `gcc-config -l' ?

I am merging gcc-4.3.4 now. It is why gcc is now 3.4.6.
What happens if you switch back to 4.4.1? Will gcc-config complain?
No: # gcc-config x86_64-pc-linux-gnu-4.4.1 * Switching native-compiler to x86_64-pc-linux-gnu-4.4.1... >>> Regenerating /etc/ld.so.cache... [ ok ] * If you intend to use the gcc from the new profile in an already * running shell, please remember to do: * # source /etc/profile And it even work now. It is compiling fftw now. I guess that some dep get lost during "emerge --depclean". And that "revdep-rebuild" with gcc-4.3.4 fixed it.
That's good news. Looks like this bugreport may become closed. [anyone with proper permissions?]
