added functions sanei_thread_sendsig() and sanei_thread_get_status()
changed behaviour of sanei_thread_waitpid(), changed parameters
of sanei_thread_begin()
pthread support after all the tests. If libpthread isn't available, try if libc
supports pthreead_*. Use macro USE_PTHREAD to check if threads are used in the
code.
pthread support, added switch --enable-fork-process which toggles
between the usage of fork and pthread, set the default behaviour to
pthread usage on Darwin
* include/sane/config.h: added the HAVE_LIBPTHRAD stuff
* sanei/sanei_thread.c include/sane/sanei_thread.h: fixed compilation issue
on OS/2, added support for fork too, so that we can use sanei_thread
functions in any case.
* backend/plustek.[ch]: changes due to the sanei_thread-lib work
added linker option -lpthread if pthread.h is found
* include/sane/config.in.h: added HAVE_PTHREAD_H
* sanei/sanei_thread.c include/sane/sanei_thread.h: added pthread_
functions to library, so every backend is able to use either fork or
pthread for its reader-process - see plustek backend for example
* backend/plustek.h backend/plustek.c: added sanei_thread stuff to support
threading on MacOS X
* backend/plustek_pp*: some cleanup
* include/sane/sanei_pa4s2.h, sanei/sanei_pa4s2.c: New sanei_pa4s2
version supporting both raw IO and libieee1284. If you don't
have libieee1284 installed, you need to enable raw IO when
running configure

instead of allocating on stack to avoid crossing 64k borders due to
restrictions of 16-bit device-driver. Cosmetic changes and some casts to
reduce compiler-warnings. Patch from Franz Bakan <fbakan@gmx.net>.
(Linux). Without this fix, especially long running commands and command
queuing would cause memory corruption if the buffer was invalid after the
flush command.
* sanei/sanei_pa4s2.c: added some #ifdefs to make it compile with
the Intel C++ Compiler (icc). The icc cannot expand assembler
inline macros (at least not with -ip)

sanei_usb_find_devices is called. Also only devices that really exist are
opened. These changes fixe the slow detection of devices on systems using
devfs or old scanner drivers.
