dkproto.h - preprocessor definitions for prototypes

=head1	SYNOPSIS

  #include <dkproto.h>

=head1	DESCRIPTION

The dkproto.h file defines preprocessor macros to allow the
use of either ANSI-C prototypes or K&R C declarations.

In a header file one can use i.e.

  #include <dk.h>
  ...
  int strcmp DK_PR((char *left, char *right));

to declare a function.

In the module itself use

  #include <dk.h>

  int strcmp DK_P2(char *,left, char *,right)
  {
  ...
  }

Depending on whether or not DK_HAVE_PROTOTYPES is defined to 1 the macros
are expanded to either

  int strcmp(char *left, char *right);

  int strcmp(char *left, char *right)
  {
  }

or

  int strcmp();

  int strcmp(left, right) char *left; char *right;
  {
  }
