This would be the right test, if you want to test for "power-pc
like". POWER and PowerPC are different processor architectures,
IBM pSeries machines (now System p) have POWER processors; this
is the predecessor of the PowerPC architecture (where PowerPC
omitted some POWER features, and added new ones). Recent POWER
processors (POWER3 and later, since 1997) are apparently
PowerPC-compatible. Still, AIX probably continues to define
_POWER for backwards-compatibility (back to RS/6000 times).
