Hello, I am having problems getting gcc to compile on AIX 7.1. Specifically, it seems to go ok through stage 1, however it hangs at stage 2 when invoking xgcc (which seems to invoke cc1 and hangs). The build log looks like this: ..... mkdir -p -- powerpc-ibm-aix7.1/libgcc Checking multilib configuration for libgcc...

It does not look to contain anyting too bad as far as I can tell.

I have been trying for the last 2 days without any progress. Some more info: - I tried to bootstrap using a gcc 4.3.3 built fo aix 5.3 (had to remove fixincludes and patch cstdio to make it work). It hags - I tried to bootstrap using gcc 4.6.3 built for aix 7.1 without graphite optimizations. It still hangs About the AIX version I am using: > oslevel -s 7100-01-00-0000 Thank you for the help, Andrei
