Yeah.  I've not done a full emerge --emptytree world with -combine in my
CFLAGS, so while I know it doesn't kill a majority of packages, it
apparently does kill a few.  Still, for the additional optimization it
enables, I consider it worth it on the others.

The latest ~arch portage fixed a few circular dependency and other
dependency resolution issues.  It wasn't uncommon to have a few packages
fail on emerge --emptytree, the first go round, due to these issues.  The
fixes now in portage are said to fix the most common such issues, but may
not fix them all.  What that all means here is that a few instances of
having to invoke --skipfirst isn't unexpected, and likely weren't due to
anything in the new CFLAGS or whatever.  Hopefully, as a portage with the
new changes eventually moves into stable, there will be fewer of those
--skipfirsts necessary.
