Function level variables are output when we output debug info for the 
function_decl.

This, in turn, is called from rest_of_decl_compilation, which is called 
from various places in c-decl.c, ada/utils.c, etc.


Make sure it's getting called.
If it is, then make sure the VAR_DECL's have TREE_USED set.
In particular, make sure the ones you want output aren't
"DECL_EXTERNAL (decl) && !TREE_USED (decl))".
