Packages have default USE settings which can see by using the --pretend
flag to emerge. You can also specify on a per-package basis what USE flags
to set (if they are different from the default).

All of this is documented on the Gentoo site and in the portage man page
(man portage).

I would say that it is safe to put mysql in USE in /etc/make.conf since
you most likely want most apps compiled with support for mysql.

But be sure to check (emerge -pv foo) for individual packages (at
/least/ the first time you install them).

An example from my system, which may or may not be relevant for you, is
that I compile php with mysql support (I have mysql in USE in make.conf)
but since I've had problems with dspam using mysql as a data store, I
disable it for that package.

sjs@diavolo ~ % grep dspam /etc/portage/package.use
mail-filter/dspam -mysql
sjs@diavolo ~ % egrep '(mysql|USE)' /etc/make.conf
USE="mmx 3dnow sse java imap maildir mbox apache2 mysql sasl xosd

Hope this was useful.

-p or --pretend does not reveal the use flags, you need to use -v for verbose,
along with the -p flag will show you which use flags are currently set and
which are not utilized.
