Reason enough to ignore gcc-current for kernel use for now. It's doing well for userland however so we'll also have to use two compilers from now on, one for kernel and one for userland. Btw, I've now placed srpm and i386-linux rpms of a new release of the egcs-1.1.2 Linux/MIPS crosscompiler on oss.sgi.com. Users of the 64-bit kernel, read Origin users should also update as this release has several fixes. Ralf
