This patch is wrong. What everyone who has commented on this
thread is missing is that AIX default to "common mode", which means that
it cannot assume the existence of PowerPC single-precision floating point
instructions. If one uses -mcpu=powerpc, the IEEE tests pass on AIX, but
one cannot assume AIX is running on PowerPC and not the older POWER
architecture.
