Uh, because they're the wrong types, so if you start coercing them into
one another things are going to go wrong.

If the prototype for your function is 

    T *X::find(const H &) const;

then you'll have to pass it an object of type H, or one derived from
type H.

This is standard C++, by the way, and has nothing to do with DJGPP.
