I would like to get some of my work into trunk, but:
1) trunk does not build as-is on powerpc-darwin8 (gcc-4.0)
2) the set of patches that workaround unsupported compiler issues
 	are not acceptable to trunk
3) the patches that I wish to cherry-pick (such as PPCMachObjectWriter)
 	would requires someone else to test against trunk
 	(I need a volunteer here)

Judgment call for the core-team, and potential reviewers:
Would a far-from-complete PPCMachObjectWriter be accepted on trunk, with 
the caveat that it is highly experimental?  This would allow 
cross-compilation to PIC mach-o/PPC objects.  I think I could extract out 
this part of my branch into a patch for review.  I need to take the time 
to write some test cases for it.
