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.

No. There is no need to re-emerge when upgrading from gcc-4.3.x to
4.4.x, the ABIs did not change.
