It probably just is one of those silly:

#ifdef SIOCGIFCOUNT
	ret = try_to_use_SIOCGIFCOUNT();
#endif

type code blocks that we find in just about every wonky
source tree out there.

There is no reason to add an implementation of it, and
the compat layer should just return the same error
code that the non-compat code will.
