I don't have enough context to be sure the following is the problem, but in
this case:

struct x{
int foo(int,int) {};
void z(){ set( &foo ); }
};

with Borland extensions on, Borland C++ treats &foo as a bound "closure__"
to this->foo. You need to say set( &x::foo ) to get a straight member
function pointer. I've never been sure how ANSI compliant that was..

De-lurkingly yours,
