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
(patch from Malcolm Parsons <malcolm.parsons@virgin.net>)
* configure.in configure include/sane/config.h.in: added detection of
machine/cpufunc.h and i386_set_ioperm() for FreeBSD support.
to copy it over and over again. Changed header inclusion order in backend
files to include backend.h after sanei_backend.h. Based on a patch from stef
<stef-listes@wanadoo.fr>.
* 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
/** Initiate a interrupt transfer read.

keep similar tests in one group. Moved more complicated tests to
acinclude.m4. Added explicit test for build and host system type. When
checking for programs, used $EXEEXT (hopefully fixes OS/2 gettext
misdetection). Removed obsolete macros. Removed PTAL check. Used autoconf for
asm/io.h check. Shortened --enable-foo output and formatted it
correctly. Translations were installed even if --disable-translations was
set. Don't test for msgcat anymore. Tell why translations aren't
installed. Used autoconf 2.5 syntax for AC_OUTPUT and AC_CONFIG_FILES. Make
sane-config executable. Print flags and installation directories near the end
of configure output.
