[gentoo-user] USE flag question

[»Q« <boxcars@gmx.net>]

A few days ago, I used eselect to switch profiles, from
default-linux/x86/2007.0/desktop to default/linux/x86/2008.0/desktop.  

A lot of USE flags were removed from my make.conf, including
the cpu-optimizations such as sse and mmx.  After re-compiling a few
things and getting warnings from the ebuilds that video and audio 
playback would be choppy without those flags, I put them back into my
flags in make.conf.  If I use ufed to manage the flags, as I'm used to
doing, it takes them back out when I save changes.

It seems strange to me that the profile switch should affect these
flags.  I think I'm overlooking/misunderstanding something, but I'm
not sure what to ask.  Any enlightenment (including links to
enlightenment) would be appreciated.
