You could contribute it back if you wanted to, but you would have to
rebase the patch to the open anoncvs tree, not eCosCentric's tree. But
in some respects it does not necessarily help you. You want the
patches in the next tree you get from eCosCentric as part of your
support contract and there is no guarantee eCosCentric will pull the
changes from the open anoncvs tree into there eCosPro tree. So you end
up contributing it to both to get the most advantage out of it.
