Hi to all,

While trying to build gcc 4.0 on an iSeries V5R3 using PASE (aix 5.1 emulation),
with a gcc 3.3.4 () got the following :

gcc 3.3.4 specs :

Reading specs from
/QOpenSys/usr/local/bin/../lib/gcc-lib/powerpc-ibm-aix5.1.0.0/3.3.4/specs
Configured with: ../gcc-3.3.4/configure --disable-nls
Thread model: aix
gcc version 3.3.4


configure used to build gcc :

../gcc-4.0.0/configure powerpc-ibm-aix5.1.0.0

The error is
