<p>
We managed to get the sane-epson library of sane-0.73 to work for an<br>
Epson GT9500 scanner on AIX 4.2.1 with<br>
CC=cc ./configure --disable-shared<br>
using the patch appended.<br>
<p>
(Note that this _includes_ a patch by Christian Bucher for a GT9000<br>
which has been posted earlier this month).<br>
