This turned out to be my mistake; as Ludovic implies, you need to
replace the whole of the asis-2010 gnat/ directory by the corresponding
files from the compiler you're actually using.

I still think that if the tree format version number hasn't changed you
shouldn't get Tree_Format_Error exceptions! but everyone's human, after
all.

There are a couple of things in the ASIS code that aren't supported by
GCC 4.6; "Name_Implemented_By_Entry" and "Is_Overriding_Operation". Not
sure how these will affect users, though.

I'll be writing this up properly soon.
