Steven,

Sorry, this thread is a bit old, but I'm back from vacation now --  
thanks for your help.

I took your hint that I should change to the version of boost.build  
that ships as part of boost 1.37.0, and this fixes the MSVC 9  
problem.  However, it also breaks my Macintosh build.  Using the  
toolset darwin-4.0 and the version of boost.build posted at [1], my  
jam files build my project just fine, but using the version from boost  
1.37.0 I get the following compiler error:

    cc1plus: error: unrecognized command line option "-fcoalesce- 
templates"

This command line option is indeed unrecognized by GCC starting with  
version 4.0.0 (I'm using 4.0.1).  Diff'ing the two versions of the  
tools/darwin.jam file, I can see where this:

     # GCC 4.0 and higher in Darwin does not have -fcoalesce-templates.
     local gccversion = [ SHELL "$(command) -dumpversion" ] ;
     if $(gccversion) < "4.0.0"
     {
         flags darwin.compile.c++ OPTIONS $(condition) : -fcoalesce- 
templates ;
     }

changed into this:

     # - GCC 4.0 and higher in Darwin does not have -fcoalesce- 
templates.
     if $(version) < "4.0.0"
     {
         flags darwin.compile.c++ OPTIONS $(condition) : -fcoalesce- 
templates ;
     }

Was a darwin-specific bug introduced here in the transition from [1]  
to boost 1.37.0?

Thanks,

Ian
