What does not work in FC5+ is: 1) most of programs/libraries built against glibc 2.0.x, i.e. built on RHL 5.{0,1,2} or something equivalent, that's more than 8 years old 2) buggy programs that don't include <errno.h> when they are using errno or don't include <netdb.h> when they are using h_errno and instead declare it themselves. They are just broken and need to be fixed, I think even RHL9 didn't allow you to link such broken programs. 3) programs/libraries that rely on LinuxThreads non-conformance to standards (such as hardcode knowledge about the stack layout LT used, or that different threads used to have different pids and crap like that) Jakub
