[sane-devel] snapscan (agfa 1236s) not working since 1.0.4

[Michal Maruška]

a few months ago i upgraded my 1.0.4 version. The agfa 1236s scanner stopped
working (hp 4c works well). Till now i have had to use the old version for that
model.

Broken sane says:

The old version 1.0.4 (compiled 21/2/2001) works ok. Another 1.0.4 from June
2001 does not work. I don't recall the difference between those 2 compilations, sorry.

Today I tried to recompile the 1.0.[234] versions but i get:
