i've tested o32 and n32 a little bit with GCC 4.8.  it seems to
work at least as poorly as GCC 4.5 for me.

if you see specific GCC 4.8 regressions vs. 4.5, please file PRs
about each issue, so we can at least investigate them from the
compiler POV.

you probably don't want "int10" on non-x86, IIRC?

interesting; this symbol shouild be provided by the Xorg server itself.

Mac, this reminds me of a PPC issue we've seen?

that seems strange.  i don't tend to use etcupdate (just postinstall),
can you confirm they're GCC 4.8 specific?
