Improving here means do not set LIBS/CFLAGS if library is not detected.
This prevents some unknown options based to ld when host is Linux and
target is mingw32/64. Further improvements are needed if one wants this
snmp support when cross compiling to really work.
Also, to make commit bisectable, updated all autofoo files using
'autoreconf -i -f' and repatching ltmain.sh.
Also, test-driver was missing from git repo but the Makefile.in
checked in expected it to exist.
Original logic was confusing the DLL creation process.
Each backend was creating a DLL of name libsane-1.dll;
overwriting each other each time. Since libsane is built
last, you could never get access to other DLL's like
you can on unix platforms.
Windows doesn't use soname concept anyways. You can copy any
libsane-*-1.dll to libsane-1.dll into same directory
as scanimage.exe and it will work as expected for that
one backend.
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.
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.
os but AIX. Use "normal" shared libs (.so) instead of archives on AIX. Use 1
instead of 2 as major number with Irix.
