 * ANSI Compiler Support

 * David Harrison
 * University of California, Berkeley
 * 1988
 *
 * ANSI compatible compilers are supposed to define the preprocessor
 * directive __STDC__.  Based on this directive, this file defines
 * certain ANSI specific macros.
 *
 * ARGS:
 *   Used in function prototypes.  Example:
 *   extern int foo
 *     ARGS((char *blah, double threshold));
