Re: [BUILDROBOT] gcc21 fails to build tilegx-linux

Thanks for the bug report. I have not been able to reproduce the link error in my environment, but I've committed a change to use g++ instead of gcc and I will see if the buildbot does better with that change. The other issues I will fix when gcc is in stage 1.

The fprintf() warning could easily be silenced with a "%s". The next
two warnings can also be cured with simple casts. However, I'm not
sure about the linking error. `-lstdc++' is there, maybe it's too
early? Or just compile/link it with g++ instead of gcc?
