Hi,

please check the patches
	gdb-6.3-threaded-watchpoints-20041213.patch
	gdb-6.3-threaded-watchpoints2-20050225.patch
in
	http://download.fedora.redhat.com/pub/fedora/linux/core/development/source/SRPMS/gdb-6.6-8.fc7.src.rpm

Going to check there some recent Linux kernels compatibility problems, though.
