Function pointers and Borland C++

Borland C++ seems to have a bug regarding template argument deduction when 
dealing with function pointers. Consider this:

template<typename T> void set(const T& t);
int foo(int, int) {};
// ...
set(&foo);

When calling set(&foo), we should get T = int (*)(int, int). Then the 
parameter t has type reference to const pointer to a function taking two int 
parameters and returning an int.

However, Borland C++ won't perform this deduction (all other compilers I 
tried - GCC, Comeau, and MSVC - seem to do it properly. A workaround is to 
use this form of set():

template<typename T> void set(T* t);

Where it deduces T a function taking two int parameters and returning an int. 

This appears to be a Borland-specific problem, but should it be part of 
config.hpp? Any suggestions on what to name this problem?
