Yes, that's the problem.  There is another way:

  rule format-rtlink ( toolset variant : properties* )
  {
      if [ MATCH .*(metrowerks).* : $(toolset) ] || 
          [ MATCH .*(cwpro).* : $(toolset) ]
      {
         return <runtime-link>static $(properties) ;
      }
      else
      {
         return <runtime-link>dynamic $(properties) ;
      }
  }

Now add format-rtlink to the requirements.

Yeah.

So maybe I got it backwards.  How terrible is it to always link
statically on NT?

I think it is.

That wouldn't work, sorry.
