What do you mean, "of course"?  That is a perfectly valid C construct and
is in fact quite common.

Some deficient compilers do have a problem with such constructs, and there
are a number of work-arounds possible.  One is

struct event;	/* incomplete type to get entry into symbol table */
struct event {
	struct event *next;	/* should be accepted now */
};
