building gcc/g++ 3.0 on aix: gen-num-limits failed to execute

["Paul DeMello" <paul at oax dot com>]

I'm having problems building libstdc++-v3, I believe.

My system:

os:  powerpc-ibm-aix4.3.3.0
binutils:  2.9.aix43.010216 (as recommended on the gnu gcc site)
make:  GNU Make version 3.77
gcc -v:   (I had installed just gcc 3.0 before (not g++), successfully)
Reading specs from /usr/local/lib/gcc-lib/powerpc-ibm-aix4.3.3.0/3.0/specs
Configured with: ./configure
Thread model: single
gcc version 3.0

What I did:

./configure --enable-threads=pthreads
nice /usr/local/bin/make bootstrap-lean

Eventually, after a few hours, I get:

Hope someone can help...  Thanks.. :)
