[Boost-build] [v2] Accumulating cxxflags in user-config.jam

Hi,

I have several project Jamfiles that set <cxxflags>.  In addition,  
our user-config.jam declares a toolset with some additional  
<cxxflags>.  It seems that either one or the other set ends up  
getting used, but not both.  Here's an example.

In a project Jamfile, I've set the project requirements and usage- 
requirements to

<toolset>vacpp:<cxxflags>-qidirfirst

In my user-config.jam I have the vacpp toolset declared like this

using vacpp
   : 7.1
   : /usr/lpp/ppe.poe/bin
   : <fflags>"-q64 -w -qsuppress=cmpmsg"
     <cflags>"-q64 -w"
     <cxxflags>"-q64 -w"
     <arflags>"cs -X64"
     <find-shared-library>xlf90
   ;

When I build, I lose the project Jamfile <cxxflags>.  Is there some  
way to combine the project Jamfile <cxxflags> with those in the user- 
config.jam so that when the init rule is called, the full set of  
options is present?

Thanks.
