Have a look at the "Locks and threading" section of
http://www.wangafu.net/~nickm/libevent-book/Ref1_libsetup.html

Excerpt:
=========
To get locking in Libevent, you must tell Libevent which locking
functions to use. You need to do this before you call any Libevent
function that allocates a structure that needs to be shared between
threads.

If you are using the pthreads library, or the native Windows threading
code, you’re in luck. There are pre-defined functions that will set
Libevent up to use the right pthreads or Windows functions for you.

Interface:

#ifdef WIN32
int evthread_use_windows_threads(void);
#define EVTHREAD_USE_WINDOWS_THREADS_IMPLEMENTED
#endif
#ifdef _EVENT_HAVE_PTHREADS
int evthread_use_pthreads(void);
#define EVTHREAD_USE_PTHREADS_IMPLEMENTED
#endif
