   conditional defines: 

   MAIN
     should be defined in just one file that will contain the fn definitions and variables

   USE_SNPRINTF 
     emulate snprintf on Win platforms (you will
     lose the security which is provided under unix of course)

   SOCK_ERRORS
     include error code handling and checking functions
