But then you lose the ability to do some sanity checking.
You can type

in some condition (maybe even deeply nested)
and have a hard time finding out why Boost.Build does not apply your
settings. (This is the current state and I'm not quite happy with it,
although it has not bitten me yet ;-) )

So I think that there must be some way to tell Boost.Build that it just
"knows" some special properties, so it can do something sensible with
them, even if it is "only" some "syntax" checking.

And I think this also applies to <target-os>, <host-os> and maybe
something else, too.
