Assuming this one will get in today, I've pushed a few more topics to my 
gitorious clone which are up next.

* LINK_INTERFACE_LIBRARIES-genex

Make the LINK_INTERFACE_LIBRARIES properties genex capable. This is far 
easier than introducing a new INTERFACE_LINK_LIBRARIES property, and gets us 
to the position that includes, defines, and linked libraries can all be 
determined by generator expressions in plumbing API. The new 
INTERFACE_LINK_LIBRARIES property was only to be added for consistency with 
other INTERFACE properties, and I still think it should be added later.

* INTERFACE_POSITION_INDEPENDENT_CODE

Allow dependees to determine the value of the POSITION_INDEPENDENT_CODE 
property of a target.

I also pushed a INTERFACE_PROPERTIES branch which will follow on from this 
one, but we can mostly discuss that one later.

Thanks,

Steve.
