As this is in sanei/sanei_ab306.c I guess it's up to me :-/
This fallback is used in quite some other files and seem to "work"
everywhere else. However, I have no idea for which system it's
necessary. My Linux system seems to have sys/io.h. Maybe pre-glibc2
systems?

I don't have this header, but isn't this a bug in the header file?
Or are the asm files kernel headers and should never be included?

This Debian build page is very interesting anyway.
Another failed build was on Alpha:
scanimage.c:1564: incompatible type for argument 2 of vprintf'
This is fixed in CVS.

Yet another one is on MIPS:

checking host system type... ./config.guess: 1: command not found
./config.guess: unable to guess system type This script, last modified
2001-12-13, has failed to recognize

Looks suspicious. Or does this really mean, that Linux/Mips wasn't
known by this version of config.guess. I'm just nervous beacuse of the
"1: command not found".
