I completely agree.  As I tried to explain in the bit you snipped (maybe I
wasn't very clear) I also think that the plugin can get all the information
it needs from the target hooks.  The question is whether it is nonetheless ok
to apply this to the gcc-4.5 branch in order to make things easier for my
users, even though it is technically the wrong thing to do in the long term.

Ciao,

Duncan.
