That's exactly the right fix. As a bit of background, long time ago all 
toolsets had to declare 'version' subfeatures on their own. Time passed, and 
new 'common.check-init-parameters' function was added that declared 
subfeatures automatically. Apparantly, the sun toolset was not fully 
transitioned to use the new mechanism.

Fixed now on trunk and branch. Thanks for report and suggested fix!
