GPC and UNIX Curses

Use the `asmname' directive to access them.  Their *Pascal* names
must of course differ.

> 
> 	extern int colors();

> 	(* in Pascal *)

        Var
          ColorVar: __asmname__ 'COLORS' Integer;

        Function ColorFunc: Integer; asmname 'colors';


Sorry for the underscores and the different syntax for variables and
functions.  I already suggested to replace `asmname' with something like
`external name',

        Var
          ColorVar: Integer; external name 'COLORS';

        Function ColorFunc: Integer; external name 'colors';

but I did not yet work on this.  (See the GPC list archives, starting with
7 Sep 1996, for a discussion about pros and contras for different ideas for
the syntax for external name specification.)

Hope this helps,
