powerpc-ibm-aix5.2.0.0 bootstrap failure

[Steve Edwards <edwardss at whl dot co dot uk>]

I have been testing the current SVN version of gcc (mainly for the
Fortran development) but had a build failure on a recent clean
bootstrap under powerpc-ibm-aix5.2.0.0

gcc version:
gcc (GCC) 4.3.0 20070706 (experimental)
Copyright (C) 2007 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is

Configured as:
/home/user/gcc/configure --mandir=/usr/local/share/man
--infodir=/usr/local/share/info --with-gmp=/usr/local
--with-mpfr=/usr/local --enable-languages=c,fortran --disable-multilib
--disable-nls


Error was:

To build I had to apply the following:

Note that I am not certain as to whether this is anywhere near
the correct thing to do, but it did enable me to complete the
bootstrap. I certainly have not experienced this on any ix86 bootstraps.

With that change I had the following from 'make -k check'

Has anyone else come across this type of thing before and does anyone
have any better suggestions for solving the problem?
