That is some precious info. I'll remember that when switching next week, thanks.
I will not have much problems with dependencies/blocks and stuff
because I already switched the whole tree to ~x86, masking some
blocks, so, now it is just a matter of recompiling stuff. Anyway, If I
switch, do the emerge -e system and world and eventually stop, nothing
will (in theory) be broken as long as I mantain compatibility
libraries right? I'll switch from 3.4.5 to 4.1, dunno if there were
substancial changes like when switching from 3.3 to 3.4. Anyway, gotta
read the gcc upgrade guide again.
