[gnu.gcc.bug] address constant bug?

drf@SUN.COM (David Fuchs) (10/16/88)

The following program causes a compile-time error message from gnu-cc
version 1.29.  K&R 2nd ed., A7.19 seems to imply that it should be OK.

/* A wonderful macro for finding the byte-offset of a field in a struct: */
#define OFFSET(type,field) ((int)&((type *)0)->field)

typedef struct {
	int i;
	short s[100];
	} foo;

int offsets[] = {
 OFFSET(foo, i),
 OFFSET(foo, s), /* This works ok, but the next line results in... */
 OFFSET(foo, s[0]), /* "initializer for static variable is not constant" */
 0
};
