HI,

For some reason my follow-up hasn't made it through.

I missed that you're on AIX.  So either you're using an older version of
GCC to bootstrap, or IBM's xlc/xlC compilers to bootstrap.

Here is a thought I had up re-thinking this.  This might be an
architecture problem.  Which version of the POWER chips are you using?
YOu might have to force the GCC configuration process to use -march to
specify the right processor.  But as far as I know, the configure script
should be smart enough to figure that out.

It's been about ten years since I used the xlc/xlC compilers, so I am
not sure how one would select the architecture they want.
