If your are using the C++ parser you must declare all exportable functions with 
extern "C" FAR PASCAL ...... because PASCAL alone will not switch off the C++ 
name mangling. 

But if you only export callbacks in an exe there are simpler methods:

1. use the keyword _export in together with FAR PASCAL. BC will export the 
function automaticly, you  need not list it in the EXPORT section of a DEF 
file.
2. If you do not compile a DLL, you can switch on "smart callbacks". Then you 
don't need exports or a call to MakrProcInstance for your callback functions.
