[sane-devel] sane-backends fail to build on Linux/hppa

[Petter Reinholdtsen]

Checking the Debian autobuilder logs, I discovered that sane-backends
fail to build on Linux/hppa.  The error message seem to be related to
the inclusion of <asm/io.h>.  Apparently <sys/io.h> is missing bug
<asm/io.h> is present and useless.

It do not seem like a god idea to use <asm/io.h> as a fallback.
Anyone know how to solve this?

The full build log is available from
<URL:http://buildd.debian.org/build.php?pkg=sane-backends&arch=hppa>,
but this is the failing part:
