Sorry, my review was too superficial.
I did downgrade my flex to see if your changes affect the scanner,
but I did not test it without your patch and also did not have a look in
what the changes are.

The changes I noticed here are probably related to the flex package I
use (on a Gentoo system) -- they even occur without your patch.  I'll
attach what I noticed in case someone is interested.
