I hadn't thought about that, but come to think of it, I think you are
indeed correct.  I'll have to check, and may just be removing it, as my
CFLAGS string is certainly long enough without it! <g>

Ahh... I had wondered about that, and seen hints to that effect, but no
direct statement.  Good to know!

I should probably look it up and see what the status is...  AFAIK, eselect
compiler is mostly working, but it still doesn't handle the conversion
from gcc-config correctly on amd64 (and I noticed recently, with the
gcc-4.1 snapshots, it doesn't remove the old config when the snapshot is
upgraded, but I haven't looked into it).  IIRC, tho, JH said he wasn't
going to have much time for awhile, due to school I think it was, so
that's kinda in suspended animation ATM.

Good news indeed! =8^)  Looking forward to it!

...  I've been thinking about joining the portage list, and in fact have
it subscribed here in PAN (on gmane), but I haven't actually had time to
go thru the list history and get in context.  Likewise with the docs list,
as a number of folks have suggested I'd be good at that, what with my 600
line posts and the like.  <g>

Probably my reason -- you just can't see from the manpage what use it
would be to you. =8^)

I /think/ I noticed Spyderous using it, and anyone that can maintain the
complexity that's xorg certainly gets my respect.  I've been looking for a
good non-disruptive excuse to ask him, but haven't yet found one,
unfortunately.
