Agreed.  I guess my remaining questions are for AIX and mipsisa64-elf.

Can someone please confirm that mipsisa64-elf is a cross-compile-only target 
and therefore not relevant for host-based MPC portability testing?

And do we want to update aix5.2 to aix5.3 in our platforms list?

        Thanks,
