[Libevent-users] [PATCH] TAILQ_ENTRY missing in evhttp.h on linux

[Paul Fisher]

In using the latest 1.3e on linux, evhttp.h fails to compile because of a missing definition of TAILQ_ENTRY in evhttp.h.  This is due to the fact that the workaround in event.h is #define'd and #undef'd within event.h and not available to evhttp.h when defining "struct evhttp_request".  This patch obviously fixes it:

 struct evhttp_request {
+#if defined(TAILQ_ENTRY)
 	TAILQ_ENTRY(evhttp_request) next;
+#else
+struct {								\
+	struct type *tqe_next;	/* next element */			\
+	struct type **tqe_prev;	/* address of previous next element */	\
+}       next;
+#endif
 
 	/* the connection object that this request belongs to */
 	struct evhttp_connection *evcon;

... but it would be nice if this was coordinated with the definition in event.h, possibly by simply not #undef'ing it from event.h.  Anyway, if there is a preference on how to fix this, I'd be glad to regenerate the patch.
