ignore them

Comment 2 Joshua Kinard gentoo-dev

Better to file this with upstream development.  It basically just means gcc's
reserving some minor memory space for variables that'll never get used.

Yes, thanks for both responses.  Will drop a line.  I'm kind of new to how the
developers work, wasn't sure whether you have working relationships with upstream.

Comment 4 Joshua Kinard gentoo-dev

Some we do, some we don't.  Depends on the upstream's tolerance of us (to put it
one way).
