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.
