* Searches the list of pre-defined line_name's and returns the number
* associated with a "match" on lname. A match means that the the characters
* of lname are all found plus, optionally, digits. If no match is found
* the value unspecified_int4 is returned.

* dup_name - returned TRUE if there is an identical name match OR (there
*	     is a pattern name match AND the guts are identical)
* dup_guts - returned TRUE if there is a pattern name match AND the guts
*	     are identica


* V510 *sh* 4/00
* V6.74 3/12 *acm* cleanup ifdefs and unnecessary include files
* V6.95+ 11/15 *sh*  when dup_guts is found do not return immediately -- 
*                    instead continue through the axes to see if there may
*                    also be a dup_name. This for special needs of creating
*		     an aggregated T axis by modifying the axis of the 1st file
*
