I understand. If what you want is to show this on the regression tests, 
update the status/explicit-failures-markup.xml

<library name="thread">
<mark-unusable>
<toolset name="*como-4_3_3*"/>
<note author="B. Dawes" refid="10"/>
</mark-unusable>

If what you want is to avoid the build completely, I could not help you 
too much. Perhaps you could define a specific rule that uses

     if ! <toolset>sun in $(properties)
     {
       ...
     }

At a last resort you could add some code to report a clear error when 
__SUNPRO_CC is defined.

Best,
Vicente
