Comment (by carter):

 ok, i managed to build stage2 successfully with apple clang from apple dev
 tools xcode 5 preview, the newest version made available as of august
 21st. (ie the version released yesterday).

 I used
 {{{
 CC=pathtoclang ; ./configure --with-gcc=pathtoclang
 }}}
 (note: i should have treally tried it without the CC=pathtoclang, but i've
 not had the time )

 I'm running the test suite now. I'm seeing some funny errors, I'll attache
 the reports in a little while once the test suite ends. (its taking a
 while to run it all!)
