-/* Linenos are processed on a file-by-file basis.
-
-   Two reasons:
-
-    1) xlc (IBM's native c compiler) postpones static function code
-       emission to the end of a compilation unit. This way it can
-       determine if those functions (statics) are needed or not, and
-       can do some garbage collection (I think). This makes line
-       numbers and corresponding addresses unordered, and we end up
-       with a line table like:
-       
-
-		lineno	addr
-        foo()	  10	0x100
-		  20	0x200
-		  30	0x300
-
-	foo3()	  70	0x400
-		  80	0x500
-		  90	0x600
-
-	static foo2()
-		  40	0x700
-		  50	0x800
-		  60	0x900		
-
-	and that breaks gdb's binary search on line numbers, if the
-	above table is not sorted on line numbers. And that sort
-	should be on function based, since gcc can emit line numbers
-	like:
-	
-		10	0x100	- for the init/test part of a for stmt.
-		20	0x200
-		30	0x300
-		10	0x400	- for the increment part of a for stmt.
-
-	arrange_linetable() will do this sorting.		
-
-     2)	aix symbol table might look like:
-
-		c_file		// beginning of a new file
-		.bi		// beginning of include file
-		.ei		// end of include file
-		.bi
-		.ei
-
-	basically, .bi/.ei pairs do not necessarily encapsulate
-	their scope. They need to be recorded, and processed later
-	on when we come the end of the compilation unit.
-	Include table (inclTable) and process_linenos() handle
-	that.  */
