  maybe some parts of it should be checked in purely as cleanup/portability
enhancement, see comment below

  Should be fine I think

  We really shouldn't assume such recent features of gcc, I understand
it's useful from for coverage reports, but it really can't get in the
way for normal compilations, maybe this need to be refined a bit so that
we can keep it. I would have assumed that if --enable-test-coverage wasn't
explicitely asked for, then those bits would not need to be disabled, right ?

  Looks like a good change

 looks safe too

  Hum, we really rely on libvirt_sym.version to define the exported list,
someone may be able to help on how to do this on OS X, but as is we can't
apply it seems.

  we already include sys/un.h in xend_internal.c and proxy_internal.c
so this can't break anything, looks safe.
