Hi all,
attached is a small patch that approves some diagnostics for INTENT
declarations. It also takes care of a TODO note in decl.c.
I had regtested a previous version of the patch without problems and
will do another run with this one before checking in. Ok for trunk?
Cheers,
Janus

* decl.c (match_attr_spec): Synchronize the DECL_* enum values with the
INTENT_* values from the enum 'sym_intent'. Call 'match_intent_spec'
and remove a TODO note.
