Milestone:  Boost 1.49.0                 |   Component:  mpl      
  Version:  Boost 1.47.0                 |    Severity:  Problem

-----------------------------------------+----------------------------------
 when using boost 1.47.0 with gcc 4.1.2 and -Wundef -Werror,
 it gives the following errors

 {{{
 boost/mpl/has_xxx.hpp:344:9: error:
 "BOOST_MPL_HAS_XXX_NO_EXPLICIT_TEST_FUNCTION" is not defined
 boost/mpl/has_xxx.hpp:357:9: error: "BOOST_MPL_HAS_XXX_NO_WRAPPED_TYPES"
 is not defined
 mpl/has_xxx.hpp:386:9: error:
 "BOOST_MPL_HAS_XXX_NO_EXPLICIT_TEST_FUNCTION" is not defined
 boost/mpl/has_xxx.hpp:459:8: error:
 "BOOST_MPL_HAS_XXX_NEEDS_TEMPLATE_SFINAE" is not defined
 }}}

 This problem has been already addressed by bug report 4666, but apparently
 its part for MPL has been forgotten. Therefore I would like to resurrect
 this problem again.

 Either the logic of defining these four #define's needs to be revisited in
 the header file, or their usage must be rewritten to check whether the
 #define is defined at all. For the latter case, I'm attaching a patch.

 Should you need more information, just ping me.
