Reproducible: Always
Steps to Reproduce:

Someone on the forums told me that is was a very little problem and pointed out 
how I could fix it. I tried it and it works. 
The following patch fixed the problem for me:

diff -u -r sane-backends-1.0.13/backend/sm3600.h sane-backends.

sane-backends-1.0.15 is in portage, which compiles with gcc 3.4
