Hey, I'm not very bleeding edge man :-) I'm still afraid glibc2 (I'm slackware based Linuxoid). I'm using egcs almost everyday and the only problem I got was compilation of 6.4 with some snapshot of 6.4. I'm glad in 1.1.1 release the problem was gone. But on production servers ( I have 6 ppros ) I even never installed egcs. I hate to have additional problem but I want to test perspective tool for myself on my private computers to have own opinion.
