what you get is a CheckContext. It wraps the actual SConfBase object (your "conf") to support logging and caching functionalities. 
It still keeps the original SConfBase in its ".sconf" attribute, and you should also be able to access the environment of the 
configure context with

   context.env

which gets redirected to context.scons.env, via "__getattr__".
Does this help a bit?

Best regards,

Dirk
