I just tried cgraph to see how it works, I've never used cflow before (I
didn't even know it was part of POSIX). I don't know if this is required
by the standards, but here it goes:

When I create 2 C files:

~~~~~~~~~~~~~~~~~~
a.c:

void a(void)
{
	b();
}
~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~
b.c:

void b(void)
{
}
~~~~~~~~~~~~~~~~~~

Two very simple C files with a function call that connects the objects
together. When I run cgraph, I get this:

| 1 a: void(), <a.c 1>
| 2   b: <>
| 1 b: void(), <b.c 1>

Isn't the application supposed to resolve b as well? cflow looks like a
useful utility. Hope to see it get integrated. :-)

Yours,
