Re: Xref and find declaration of variables

["Richard F Weber" <rfweber@link.com>]

Don't know if it's a problem persay with SourceNavigator as compared to 
the C-Parser itself not registering the proper variable & keeping track 
of the scope of the current variable that's being worked with.

However, this could explain some of the hang-ups I've been having with 
the Ada Parser if the database back-end doesn't do associations correctly.
