I am trying to compile Jove 4.13 on a Gould running UTX/32 2.1.
I am currently using 4.12 (which I also compiled).  The glitch is
that an == compare between pointer to functions is giving the compiler
grief.  The only relevant lines that I can find (those involving 
the commands variable, and the Forget function; see below) I have
changed back to their 4.12 versions (which, for example, lacked
the proto macro).  This was no go either.  I thought maybe our
compiler had changed (they did that to me before), but 4.12 still
compiles ok.  I am using the same setup in tune.h and sysdep.h
in both versions.

I am one clueless morsel.  Anybody have any ideas?

Line 346, below, is the one causing the problem.  In version 4.12, the
c_proc member was defined as

	void (*c_proc)();

but changing back to that has no discernible effect.  macros.c is 
virually unchanged from 4.12.

*** dataobj.h
struct cmd {
	int	Type;
	char	*Name;
	void (*c_proc) proto((void));
#ifdef MAC
	char c_map;			/* prefix map for About Jove... */
	char c_key;			/* key binding for About Jove... */
#endif
};
*** end of dataobj.h

*** macros.c
331- void
332- Forget()
333- {

344-		if (PrefChar(*cp))
345-			m->m_len -= 2;
346:		else if (commands[cp[1]].c_proc == Forget)
347-			m->m_len -= 1;
348-	} else
*** end of macros.c
