#4364: boost/mpl warning cleanup
-------------------------------------+--------------------------------------
 Reporter:  tatu.kilappa@…           |       Owner:  agurtovoy
     Type:  Patches                  |      Status:  new      
Milestone:  Boost 1.44.0             |   Component:  mpl      
  Version:  Boost Development Trunk  |    Severity:  Cosmetic 
 Keywords:  warning                  |  
-------------------------------------+--------------------------------------
 Some definitions in boost/mpl/has_xxx.hpp are defined to 1 on conditions,
 but never defined to 0. This causes warnings when they're later checked as
 truth values instead of defined().

 Attached patch defines them as 0 if the workaround does not match. Another
 approach would be to use #if defined() later, this is probably better.
