From 0784556690a1f33ea44a03d20312ef439ae5cc32 Mon Sep 17 00:00:00 2001

Subject: [PATCH 5/5] [fix-off-by-one-error]: generatred line numbers are off
by one
The code that is generated by flex has an off-by-one error in the
generated #line pragmas that occur after the second %% line in the
source file (that is, the one that is used after the token patterns). As
a result, gdb will think we're, e.g., on line 46 when in reality we're
on line 45.
Marcus Rausch supplied the patch in this commit
