Both  NULL  and  RAND_MAX   are ANSI C.
      (p.102)	 (p.252)    of my Kernighan & Ritchie, 2nd. ed.
      <stdio.h>	 <stdlib.h>

However, I've experienced myself and heard more than once that
SunOS 4.x.x  has always had broken header (*.h) files.
Actually I had thought that the headers that come with gcc would 
``ifdef around these''...

Anyway,  add the following lines to your  src/include/Platform.h

#ifndef NULL
#define	NULL	0
#endif

#ifndef RAND_MAX
#define	RAND_MAX	32767
#endif

(or just to the beginning of src/nmath/sunif.c).

-----------

Kurt, could we add this bug-workaround to configure.in and Platform.in
such that something like

#ifdef SunOS4
/*-- define missing ANSI C --*/
#define	NULL	0
#define	RAND_MAX	32767
#endif

---
Un(?)fortunately, I haven't had access to SunOS4 machines for more than a
year now.
