Assuming line 174 reads:
    pSymbol = GetProcAddress( (HINSTANCE) pLibrary, pszSymbolName );

Try changing it to:
    pSymbol = (void*) GetProcAddress( (HINSTANCE) pLibrary, pszSymbolName );

If this fixes the issue let me know and I will correct the master.  The
code in this win32 implementation was written for VC++ and this may be the
first time it has been used with another compiler.
