According to xanthian@zorch.SF-Bay.ORG (Kent Paul Dolan):
> oftype(x) *bsearch(const any (*x)[], const oftype(x) *,
>                    unsigned, unsigned,
>                    int(*)(const oftype(x) *, const oftype(x) *));

This kind of function declaration will never be useful unless either
(1) implementations are required to make all pointers the same size --
an unreasonable requirement for word-addressed machines -- or (2)
functions so declared, including the comparison function, are actually
defined to use |void *| in place of all the pointers to oftype(foo).

By the way, the first parameter must surely be "const any *x".
