Re: UPDATE Re: bootstrap failure of 3.0.3 on aix4.3.3

Okay - I figured out the problem below is from g++ generating WEAK
symbols, which AIX does not support.  However, the build notes for
*-ibm-aix-* word it thusly:

> The GNU Assembler incorrectly reports that it supports WEAK symbols on

I ran my configure with --without-gnu-as and --without-gnu-ld.
Also, after installing binutils, I removed gas and as from
the prefix/bin and prefix/powerpc*/bin respectively.  However,
it seems perhaps something else was left behind that the
gcc build saw that caused it to turn on the weak symbol
support.  I'm continuing to dig, but if anyone can offer
advice on what may have gone wrong I'd appreciate it.

Thanks.
