Making some progress in updating / providing
the patched GDB for Mac OS X (Tiger for now).

http://svn.dsource.org/projects/gdb-patches/downloads/gdb6.3/
http://www.opensource.apple.com/darwinsource/DevToolsNov2005/gdb-434/

Will post the final patch to gdcmac, as usual.
(need to backport it to GDB 5.3, for Panther)
