Overriding default feature behaviour

From: John Maddock (john_at_[hidden])

Is it possible for a toolset that inherits from another, to override the
default behaviour of some feature - specifically I want to inherit from
msvc-stlport-tools.jam, but have the default for <stlport-iostream> to be
"on" rather than "off".

Thanks,

John.
