The upgrade guide says yes, but this seems to be true only when the ABI changes, which happend for the last time when gcc 4.3 was introduced. I would not do the emerge -e thing. Unless this new gcc has some cool features you want to use. Then you would change your CFLAGS, and either let the changes gradually drop in, or re- emerge everything to make them happen at once. What do you people think, are there fancy new and yet save CFLAGS that would improve our Gentoos? http://gcc.gnu.org/gcc-4.4/changes.html lists some improvements, to me they don't look too spectacular. Well, maybe apart from the graphite stuff (http://gcc.gnu.org/wiki/Graphite/PolyhedralInterface) which has been mentioned here. I don't know how much of an improvement this may be. Wonko
