thanks for your answer and the patch.

I've tried your patch but it doesn't work for me:
'error: "flavor" already declared as a subfeature of "<toolset>" specific to
This seems correct, as common.jam doesn't know about the predefined subfeature
and tries to define it again. Have you also patched your common.jam?
I still think common.jam is the right place to add the 'optional'.
But as I wrote in my last mail, this results in empty build-commands and - as
I just notices - in a 'bin/gcc/debug/...' build dir. (Note the missing version
that is normally added, even when the default gcc is used.)
I guess the code that processes the subfeatures of toolset gcc doesn't handle
correctly subfeatures without default values. This looks like the actual bug
to me. But I 'm not familiar enough with boost build internals to know where
to start digging.
