Apologies if you received this mail already, I'm having problems with my

An icc profile would be welcome. I've been the maintainer of icc (and
other Intel tools) for the last year or so more by default than
real interest. I would welcome any input from the Gentoo community.
Re-adding slots and an icc profile was on my mind, but never found the
time to invest in it, and got at the tail of my priority list. So don't
hesitate to contact me (email, irc, bugs) and others.

There was some attempts a few years ago for rolling up a full Gentoo
with icc, but it hit several problems if I recall. Now both icc and gcc
have improved since then.

Also, if you haven't already, check also some of the old bugs [1,2] we
have, and a recurring one [3].

I would like to recall one important issue with the Intel license
concerning the "free for non-commercial use" [4]. It means
you can't use it for free if you're paid to use it. Yes,
beer is not free for academic scientists too.
