The call you would get is not likely to be all that useful, but it is
the one you wrote. The environment is the one you get from environment()
at the point where you would call .External2. So instead of

.External2("foo", x, y)

do

.External("foo", quote(.External2("foo", x, y)), environment(), x, y)

and adjust your C function accordingly.
