[Boost-build] [V2] Sun toolset and "version" subfeature

Hello all,

I am running into some trouble with the BBv2 Sun toolset. My user- 
config.jam looks like this:

using sun
   : 5.8
   : /opt/sunstudio11/SUNWspro/bin/CC
   ;

When I run bjam --v2 in libs/function/test, I get the following error:

/nfs/magrathea/home/user3/dgregor/Projects/boost/tools/build/v2/build/ 
feature.jam:557: in feature.subfeature from module feature
error: "version" already declared as a subfeature of "<toolset>"  
specific to sun

/nfs/magrathea/home/user3/dgregor/Projects/boost/tools/build/v2/build- 
system.jam:125: in load from module build-system

kernel/modules.jam:261: in import from module modules

kernel/bootstrap.jam:121: in boost-build from module
/nfs/magrathea/home/user3/dgregor/Projects/boost/boost-build.jam:12:  
in module scope from module

Now, if I take the "5.8" out of user-config.jam, everything seems to  
work fine. The problem seems to be this line near the beginning of  
tools/build/v2/tools/sun.jam:

        feature.subfeature toolset sun : version ;

At the risk of sounding foolish, can we just take out this line?  
Doing so makes everything work as expected, and none of the other  
toolsets seem to have it...
