  I'm doing a fresh 32-bit install on an older Dell with an AMD K8, for
experimentation.  I'm getting a build failure on gcc as listed below.  I
start off my USE variable with "-*" and then add on stuff as necessary.
A Google search turned up
http://www.gossamer-threads.com/lists/gentoo/dev/242446 where vapier
says...

  That appears to be relavant to me.  But I'm not a developer, and I
don't claim to totally understand what he's talking about.  I do have
some ebuilds that use C++.  Should I add "cxx" to my USE variable?  The
build error message follows...
