The error saying that the linker could not be found suggests that the
installation is corrupted.  Uninstall the compiler and install it again from
the Borland C++ distribution CDROM.

That source code is a mix of Win16 and Win32 code.  Use DllEntryPoint
instead of DllMain in Win32 bit DLL code.

The warnings are correct.  You are not using the function's calling
parameters.  You can suppress the warnings by placing this pragma on a line
immediately before the function

#pragma argsused

Since you are using C++ and not C there is an alternative way to suppress
them.  Omit the variable name in the function header.  For instance,

instead of

  --------------
  int FuncName(int unused1, int unused2)
      {
      return 2;
      }
  --------------

Use one of these two techniques:

  --------------
  #pragma argsused
  int FuncName(int unused1, int unused2)
      {
      return 2;
      }
  --------------

  -------------- /* works only in C++ */
  int FuncName(int, int)
      {
      return 2;
      }
  --------------
