gcc-2.95.2 on AIX with pthreads

[Radu Prodan]

Hi.

I'm trying (first time in my life) to build gcc-2.95.2 on an RS/6000 H50 (7026)
running AIX 4.3.

I configured the build using:
configure --prefix=/scratch/rprodan --enable-shared --enable-threads=posix

Finally the build fails as follows (it works though if disabling threads, but I
need pthreads enabled):

/scratch/rprodan/gcc-2.95.2/__objdir__/gcc/xgcc
-B/scratch/rprodan/gcc-2.95.2/__objdir__/gcc/
-B/scratch/rprodan/rs6000-ibm-aix4.3.3.0/bin/ -g -O2 -fno-implicit-templates
-Wl,-unix -shared -o libstdc++.so.2.10.0 `cat piclist` -lm

Any suggestions?
Thanks.
