Hi Thomas,
I think your patch is better than the status quo, since it fixes the build.
However, global_thread_id_to_ptid expects global thread numbers, which are
nowadays only used in MI, never presented to the user in the CLI. Since this
is a CLI command, it should accept the inferior-qualified format instead.
Something similar to this should do the trick (I can't test it though):
diff --git a/gdb/gnu-nat.c b/gdb/gnu-nat.c

}
If there's a more efficient/concise way to go from a thread_info* to a proc*, we
should probably use it, but I couldn't find one.
