To compile TrafficServer with libev

1. Get the libev source by either:
   a. Pull the libev source into the root of the TS source
      cvs -z3 -d :pserver:anonymous@cvs.schmorp.de/schmorpforge co libev

 OR

   b. Download libev tar ball e.g. libev-3.8.tar.gz  and extract into 
      toplevel TS source directory. Next symlink the extracted directory 
      to 'libev' e.g. 'ln -s libev-3.8 libev'.

2. Apply the patch at the end of this file (after CUT HERE) to the libev source

3. In the libev directory
  a. autoreconf -i
  b. ./configure CFLAGS="$CFLAGS -Dinline_size= -DEV_MINPRI=0 -DEV_MAXPRI=0"
  c. install normally

4. Configure trafffic server with '--enable-libev'.
