So your saying that, for you, running "make distclean; ./configure
--enable-pthread; make" doesn't correctly have USE_PTHREAD defined?

If so, do you mind emailing me your config.log and include/src/config.h?
I'll see what I can do to get it working.

It works for me... a quick code review shows snapscan-usb.c a little
suspicious because its not including ../include/sane/config.h but is
checking for USE_PTHREAD.  I didn't follow its include chain very closely
though since we are talking about pixma.
