[Q] Friend functions in a Borland 4.0 DLL?

I'm trying to make a String class DLL with Borland C++ 4.0. I couldn't 
link in the operator + function (undefined symbol). I ran TDUMP on the 
lib file and, sure enough, operator + isn't listed (although it compiles 
fine) ... neither are any other friend functions ...

From the String class declaration in the header file ...

class _CLASSTYPE String
{
   ... <other functions> ...
   friend const String operator + (const String &s1, const String &s2);
}

From the code ...
const String operator + (const String far &s1, const String far &s2)
{ 
   ... <some code> ...
}


Is there anything I can do, besides write a gazillion operator + functions
to handle different types?

Please e-mail me ... I don't know if I'll be able to check this group 
before Thanksgiving (here in the good ol USA)

Thanks a bunch,

Mark Madrilejo
