** lclint maintains a table of ctype's (its representation of
** C types) and represents types internally as an index into
** this table.  This greatly improves performance of type
** checking and saves memory.  For simple derived types, it
** is easy to find if the type is already in the table.  For
** more complicated types (e.g., functions and structures),
** we check if a type is already in the table by looking 
** backwards for matches.  The last DEFAULT_OPTLEVEL types
** entered into the table are checked.  Increasing this value
** may improve memory performance, but cost in execution time.
