Franz Sirl, the ppclinux devtool maintainer, has kindly built the current rawhide XFree86 4.3.0 srpms against gcc-3.3 from 6/18/03 on Yellow Dog Linux. He is unable to reproduce the authentication problems we see on debian under either xdm or kdm. Perhaps we build XFree86 differently enough from RedHat that only we tickled the gcc bug. However I did find out that the gcc 3.3 that RedHat uses is not a patched version of the gcc 3.3 branch but rather a special rh branch of gcc-3.3. One wonders if they would see the problem if they used the stock gcc-3.3 branch instead and if there are any fixes trapped in the gcc-3.3 rh branch that haven't been put into the main gcc-3.3 branch.
