Absolutely not.

AIX still uses DBX as the primary debugging format.  AIX supports
DWARF but the AIX toolchain does not fully interoperate with DWARF
generated by GCC.

With the extensive use of DBX by AIX and regular patches from me to
fix xcoff stabs debugging, omitting me from the cc list implies that
you really haven't done your homework.

Thanks, David
