What I don't understand is why the newlib change broke older compilers. The function has been added to newlib and the definitions in newlib are correct. If this is refering to the fact that libiberty doesn't grok automatically if a symbol has been added to newlib, then that's a problem in libiberty, not in newlib. Otherwise, if you're building an older compiler, just use an older newlib as well. Corinna -- Corinna Vinschen Cygwin Project Co-Leader Red Hat
