I built GDB (6.1) as a 64bit binary on PPC64, when I try to debug a 64bit
threaded application I get the following.

But I notice that this is fixed in the mainline CVS version of GDB, using
mainline version of GDB I get the following:

Can someone please point me to patch(s) that I can apply(backport) to GDB
6.1 to solve this problem. Any help is deeply appreciated.

I dropped them as it was getting late in the release cycle, and there 
are too many other patches needed before 64-bit PPC really starts to 
work (sigtramp, frame rewrite).  Hopefully 6.2 will be a viable for 
64-bit PPC.

However, Kevin might be interested in a backport of these and some other 
changes.
