Nothing whatsoever as far as I can tell; Libevent never defined it or
looked for it as far as I can tell.  Grep for it in the source for
libevent 1.4.12-stable, and it shouldn't be there.

In fact, AFAICT, no version of Libevent in the source repository has
ever contained the string "EV_PRI" :

[279]% git log -p origin/master | grep EV_PRI
[280]% git log -p origin/patches-1.4 | grep EV_PRI
[281]% git log -p origin/patches-1.3 | grep EV_PRI
[282]% git log -p origin/patches-1.2 | grep EV_PRI
[283]% git log -p origin/patches-1.1 | grep EV_PRI
[284]%

So if there was a version that declared or inspected EV_PRI, it
doesn't seem to be an ancestor of any current version of Libevent that
I can find.

Were you maybe using some forked version of 1.4.12-stable?

I also did a Google codesearch for EV_PRI, using ' EV_PRI[^A-Z_]
case:yes ' as my query, and got no hits.
