I'm not surprised. We haven't gotten any patches for OS/2 for a long
time.

Most backends use this:
#ifndef PATH_MAX
# define PATH_MAX 1024
#endif
Where does it break? Does it help to add these lines to the files?

We can detect the availibility of shm.h in configure and check in
nec.c/sharp.c. If both backends depend on shm (no alternative), they
can be excluded from compilation. Is OS/2 using the normal configure
script?

Could you go into more detail here?

SANE is supposed to run on any Unix platform. It's tested on Linux,
FreeBSD, Solaris, AIX and Irix. We will be happy to make it run on all
platforms but someone must test them and send patches. I can only test
the mentioned platforms.
Concerning OS/2: We can include patches for OS/2 (after 1.0.4 is
released) if they don't disrupt compilation for Unix. But the patches
must be done by OS/2 users. I have asked for OS/2 comments more than
once and nobody wanted to do the work. We (the Unix developers) can't
do it--it must be done by persons using OS/2.

What defines exactly? If some backends don't compile, just disable
them in the Makefile for now.

Are you talking about the warning parameters given to gcc? These have
been set to --disable-warnings by default for the realease. This
shouldn't break anything. If disabling warnings break compilation
something else must be broken. Please send the output of make / of the
compiler.
What do you mean by "structure parameter"?

Yes, that's correct. The new Snapscan backend can be included into
SANE after the release of 1.0.4 as discussed on this mailing list.
Thanks for your tests.
