dnl libevent check function {{{
dnl @synopsis AC_LIB_EVENT([MINIMUM-VERSION])
dnl
dnl Test for the libevent library of a particular version (or newer).
dnl Source: http://svn.apache.org/repos/asf/incubator/thrift/trunk/aclocal/ax_lib_event.m4
dnl Modified: This file was modified for autoconf-2.13 and the PHP_ARG_WITH macro.
dnl
dnl If no path to the installed libevent is given, the macro will first try
dnl using no -I or -L flags, then searches under /usr, /usr/local, /opt,
dnl and /opt/libevent.
dnl If these all fail, it will try the $LIBEVENT_ROOT environment variable.
dnl
dnl This macro requires that #include <sys/types.h> works and defines u_char.
dnl
dnl This macro calls:
dnl AC_SUBST(LIBEVENT_CFLAGS)
dnl AC_SUBST(LIBEVENT_LIBS)
dnl
dnl And (if libevent is found):
dnl AC_DEFINE(HAVE_LIBEVENT)
dnl
dnl It also leaves the shell variables "success" and "ac_have_libevent"
dnl set to "yes" or "no".
dnl
dnl NOTE: This macro does not currently work for cross-compiling,
dnl but it can be easily modified to allow it. (grep "cross").
