Warnings in vrscanl.c
100%
Description
Apply fixes for vrscanl.c to the flex skeleton, so they don't get overwritten the next time the code is newly generated.
Updated by Jan Schlamelcher over 8 years ago
The flex skeleton file for C flex (not flex++) contains GNU Autoconf dependent code that is evaluated when compiling flex for building it into the flex executable. This solution is therefore not viable.

While testing whether it is possible to disable the warnings by adding appropriate 'ofdiag' includes to the lexer file (vrscanl.l), I noticed that these warnings no longer exist in newer versions of flex. So the solution is simple: don't use the outdated flex package that ships with Debian 'jessie' if you want the warnings to go away. To be fair: the flex package that ships with current Arch Linux produces code that emits three warnings, of which one has been fixed on 25.01.2017 in the current flex developement version, which is not yet available under Arch Linux.
