Comment (by steven_watanabe):

 Use a conditional like this:

 {{{

 feature.feature threadapi : pthread win32 : optional propagated ;

 rule choose-threadapi ( properties * )
 {
     local result = [ property.select <threadapi> : $(properties) ] ;
     if $(result)
     {
         return $(result) ;
     }
     if <target-os>windows in $(properties)
     {
         return <threadapi>win32 ;
     }
     else
     {
         return <threadapi>pthreads ;
     }
 }
 }}}

 Note that this depends on <target-os>cygwin being set correctly,
 but that isn't Boost.Thread's problem.
