The following won't compile:

--------------------------------
typedef char * memory ;

struct S	{
	memory (*A)(), memory (*B)();	// this is a syntax error
};

---
but
---

Struct S	{
	memory (*A)();
	memory (*B)();
};


will.

I am still running 1.0 relE here... is this something that has been
fixed?

The headache is because the former compiles using /bin/cc and
I am trying to integrate old C code with some new C++ stuff
(this is \supposed/ to work....)

Unfortunately, the first (bad) example was not what I wanted to
say  (obviously, it won't compile)... but given:

struct S {
	memory (*A)(), (*B)();
};

(which is what I wanted to say), the compiler croaks.

It shouldn't compile; it really *is* a syntax error.

When I try it (oldC, SVR2 vax) I get 6 errors -- I think your /bin/cc is
broken.  That line should be written "memory (*A)(), (*B)();".
