Hi everyone,
I have been working on getting rid of the compiler warnings on Windows. I'm not sure if I have the proper fix for this one, so I separated it from the others.
TAILQ_EMPTY(head) is defined in extra\libevent\event-internal.h as this:
#define TAILQ_EMPTY(head) ((head)->tqh_first == NULL)
It's also defined in extra\libevent\compat\sys\queue.h as:
#define TAILQ_FIRST(head) ((head)->tqh_first) #define TAILQ_END(head) NULL #define TAILQ_EMPTY(head) \ (TAILQ_FIRST(head) == TAILQ_END(head))
As you can see, these two are actually identical, but the Visual C++ compiler still complains about them, because it doesn't understand that they are identical.
what if you just delete this whole block from event-internal.h ? In the vanilla libevent sources it's only in compat/sys/queue.h
That works fine, I'll push that instead. Much better. Thanks, Bo.
