Milestone:  To Be Determined                     |   Component:  foreach     
  Version:  Boost 1.48.0                         |    Severity:  Problem     
 Keywords:  Qt foreach                           |  
-------------------------------------------------+--------------------------
 The change to fix Ticket #6131 caused a latent bug to manifest in the
 interaction
 with the Qt header qglobal.h.

 The header replaces all instances of foreach with Q_FOREACH.
 In version 1.47 this replacement was consistent.
 In version 1.48 the move of is_lightweight_proxy<T> and is_noncopyable<T>
 to the
 BOOST_FOREACH namespace causes errors:

 c:\boost\alg_1_48_0_64\boost\foreach.hpp(169): error C2039: 'tag' : is not
 a member of 'boost::Q_FOREACH'
 c:\boost\alg_1_48_0_64\boost\foreach.hpp(169): error C2061: syntax error :
 identifier 'tag'

 A workaround is to turn off this substitution by defining QT_NO_KEYWORDS.

 This will also require replacing all keywords signals and slots with
 Q_SIGNALS and Q_SLOTS.

 It would be nice if these libs could co-exist.
