Milestone:  To Be Determined         |   Component:  build        
  Version:  Boost Development Trunk  |    Severity:  Problem      
 Keywords:  type suffixes            |  
-------------------------------------+--------------------------------------
 I've attached a patch against the development trunk that indicates what I
 believe is a problem in {{{ tools/build/v2/build/type.jam }}}.

 The comments and the code suggest that re-registering a suffix to a type
 should be okay.  I've included a snippet from the current trunk below.

 {{{
 # Specifies that files with suffix from 'suffixes' be recognized as
 targets of
 # type 'type'. Issues an error if a different type is already specified
 for any
 # of the suffixes.
 #
 rule register-suffixes ( suffixes + : type )
 {
     for local s in $(suffixes)
     {
         if ! $(.type.$(s))
         {
             .type.$(s) = $(type) ;
         }
         else if $(.type.$(s)) != type
         {
             errors.error Attempting to specify multiple types for suffix
                 \"$(s)\" : "Old type $(.type.$(s)), New type $(type)" ;
         }
     }
 }
 }}}
