Current cvs as of January 14; I don't update all that frequently.

That's the only one.  The symptom is that you get errors about gdb not
being able to fetch the registers.

My patch (I believe I sent it to gdb-patches but I'm not positive; in
any case Jim Blandy has it) makes it work on older kernels, but I
didn't make it compile on libc5 systems (I don't care about those
personally and have no way to test it anyway).
