Options were in README but removed at some point. They
are useful so add them back.
Document BACKENDS and PRELOADABLE_BACKENDS variables in
README as well as in configure --help output.
Add check for winsock2.h for socket.h replancement. Also, use this
check to add ws2_32 library. Also, switch all winsock.h references
to winsock2.h.
Add check for getuid and getpass; which are not on mingw.
Add a syslog() replacement that is basically a print(). This
is also used by vsyslog() replacement.
Comment out parts of replacement sigprocmask.c on mingw.
To support these configure.in changes, I need to rebuild all
related files with autoconf 2.68 and libtool 2.4. Hand ported
our sane-backend specific changes to newer ltmain.sh.
The following updates were made to all directories but backends.
That still needs work. There are also still some pthread issues
and syslog is missing.
Windows doesn't support SIGHUP or SIGPIPE so make that optional.
Only include socket header files when sys/socket.h is detected.
Use winsock.h on windows.
Only include syslog.h when vsyslog() was detect by configure.
Skip FD_CLOEXEC when not supported by OS (not defined).
Only include sys/ioctl.h on platforms that define it.
resmgr library is only used (optionally) by
sanei_usb and sanei_scsi. So only need to
link it in for those backends. This was
a stray piece from initial cleanup of LIBS
in sane-backends 1.0.20.

Source code was inconsistent on how they were referencing
include files in include/sane. In certain cases, sane/sane.h
and sane/saneopts.h was really including external copies (with
some preprocessor implementations anyways).
Network fds are of no use to the Avahi process and can cause the net
backend to hang when saned is run in debug mode.
This only happens if the net backend tries to connect to saned a second
time and manages to establish the connection before saned has completed
its shutdown.
There is some potential for this to also occur when saned is run in
standalone mode but it's far less probable as the window is a lot smaller.
with newer automake.
* backend/Makefile.am, tools/sane-config.in: Add missing
$GPHOTO2_LDFLAGS so library can be found.
* tools/Makefile.am: Add mising $SCSI_LIBS to sane-find-scanner.
to sane-config missed during fix to stop using LIBS to link everything.
Add back in code to move LDFLAGS out of $GPHOTO2_LIBS and into
GPHOTO2_LDFLAGS.
Global replace of u_int??_t with C9x standard based uintxx_t
in order to remove some tricky and overlapping portability logic
from acinclude.m4 and leave it in only m4/stdint.m4.
Add tools/openbsd to distribution package.
* include/Makefile.am: include files should have been installed
under sane/ directory when converted to automake.
* doc/Makefile.am: Cleanup. Use automake's built in support to
install docs within subdirectories.
add cv_ prefix to cached variable. Remove AC_ARG_PROGRAM as
automake already invokes this. When prefered AC_USE_SYSTEM_EXTENSIONS
exists, use that instead of AC_GNU_SOURCE/AC_AIX/AC_MINUX.
Cleanup socket detection more by creating only a single
SOCKET_LIBS that contains list of all optional libraries
for any socket related funciton. Make sure that checks
for socket related functions use SOCKET_LIBS when searching.
Check for getopt_long() and getopt.h. Make OS/2 use
-no-undefined (same as windows).
* ltmain.sh, m4/libtool.m4: Upgrade to libtool 1.5.26.
* Makefile.am: Cleanups to match configure updates.
* frontend/scanimage.c, include/Makefile.in, lib/getopt.c
lib/getopt1.c, toosl/sane-desc.c, include/lgetopt.h:
Rename internal getopt.h to lgetopt.h to allow using
external getopt.h when it exists. This allows to go
back to optionally compiling getopt()/getopt_long() and its
prototypes and not have conflicts with external headers/symbols.
* configure.in: Group all USB logic together and all SCSI
logic together to aid understanding of whats no longer
valid. Allow sharing enable/disable options between all
USB drivers on multiple platforms. Combined CAM_LIBS and
SCSI_LIBS since they are mutually exclusive.
Skip some USB/SCSI checks when previous tests show it will always fail.
* backend/Makefile.am, tools/Makefile.in: Combine CAM_LIBS and
SCSI_LIBS. Add missing SOCKET_LIBS to epson2. Add USB_LIB.
* saned.c: Add limits.h for PATH_MAX.
own *_LIB variables instead of $LIB so that we do not have to
link in the world to all executables. Modified SANE_CHECK_U_TYPES
to be a little more portable to platforms that use #define
for u_* types. Create SANE_CHECK_BACKENDS macro so that
PRELOADABLE_BACKENDS can also be valided. Auto-populated
PRELAODABLE_BACKENDS when detect dlopen() won't work.
Various protability cleanups.
* backend/dll.c: Make dll-preload.c a .h since its an include and
not compilable byitself.
* frontend/Makefile.in, frontend/scanimage.c, include/laaloca.h,
lib/Makefile.am, lib/alloca.c, strcasestr.c, tools/Makefile.in,
tools/sane-desc.c: Convert lib/ to automake. Create a liblib.la
for everyone to use and a libfelib.la for only frontend programs.
Make all internal programs be prefixed with sanei_ as not to conflict
with other programs libsane is linked in with that will also most
likely create similar internal utils on problem platforms.
* include/getopt.h, lib/getopt.c, lib/getopt1.c: Always compile
and link in getopt_long() but prefix it with sanei_. Its
easier to always use internal version then try to figure out what
platforms support getopt_long() and what header files to use.
* backend/Makefile.am: Convert backend makefile to automake.
Initial version that is feature parity with original but uses
specific rules instead of wildcards and only links in libraries/objs
really required. Room for more cleanup of whats linked in once
all makefiles have been converted to automake.
