That's not too terrible, I suppose. What would you be thinking for
the calls that do use call_int_hook()?

or embedded in the macro:

	rc = call_int_hook(something, goodnesses);

Oh yes, good point. The hook call already knows the name, so:

#define call_int_hook(FUNC, ...) ({                        \
        int RC = FUNC#_default;                            \
