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)

--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'
=== gcc Summary ===

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