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.
get latest fixes and use logic to not recreate _stdint.h if
no changes (to prevent unneeded recompiles).
* m4/byteorder.m4: Added support to reuse existing byteorder.h if
no changes to prevent timestamp causing a recompile.
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.
