Ok, I give up.  Why does the following (example code for a doubly-linked-
list) give the compiler warning "pointer/int conversion"?

struct aet {
	long x, y;
  	float xIncr;
	struct aet *prev;
	struct aet *next;
};
struct aet *head, *last, *this;

head = (struct aet *) malloc(sizeof(struct aet));
                            /* warning comes    ^ here */

(Manx 3.6a, compiling with cc file, linking with ln file -lm -lc
[for the floating point numbers])

The main reason I'm asking is that the program keeps guruing (the "bad
address" one) in different places, suggesting something in the program
is writing on the code.  Besides, it bugs me when code stolen straight
out of K&R, 2nd ed., produces compiler warnings.

Thanks much,
