	The 32-bit PowerPC System V ABI defines DWARF Register Number
Mapping that does not appear to be implemented in GCC or GDB.  This issue
probably requires more thought and discussion about whether PPC64 should
be compatible with PPC32 or PPC64 should be compliant with the ABI or both
PPC32 and PPC64 should be compliant with the ABI.
