It should not be that hard. There are two main ABI's for PowerPC: the  
sysv and the aix ABI. Linux/*BSD use the sysv ABI, and Mac OS, Mac OS  
X and AIX uses the aix ABI. Hence, the aix abi is already supported in  
the compiler. A libc-based rtl port based on the solaris rtl shouldn't  
be that hard either.
