AIX now supports DWARF debugging with XCOFF object files. XCOFF also has a new XCOFF_DEP_EXEMPT flag to override the default stack execution disabled. There are a lot of little changes for new AIX features. The bigger problem is GDB no longer is able to debug cc1plus on the trunk and GCC now builds as C++ by default. Thanks, David
