The -Wall flag is now always enabled (when using gcc). The -Wextra
flag (previously known as -W) and -pedantic flags are, by default,
enabled during development but disabled for releases.
All other flags have been removed.
Add GCC flag "-std=c99". Also remove GCC flag "-ansi" which is an
alias for "-std=c90" and would make the flag "-std=c99" ineffective.
This fixes all occurrences of the following GCC warning:
warning: ISO C90 does not support '__func__' predefined identifier
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.
using backend debugging using SANE_DEBUG_xxx to be used for saned controlled
scanning when using socket activation. When only the socket is received we
use the existing code path.
My previous try was always defaulting to "yes" and user
and to manually specify --disable-dynamic to work correctly
on platforms that didn't support dynamic loading.
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.
In net-snmp 5.5 the UDP transport does not provide a public-API way to extract the originating IP of the
response to the SNMP auto-detection broadcast request... The structure that stores that information
was moved to the public include/library/snmp_transport.h header only in 5.6 :(
cygwin and mingw is now hiding M_PI_2 defines with -ansi flag.
Remove to fix cygwin compile.
Mingw doesn't support fork() so default to pthreads.
Add u_short to complete definition of u_* types which helps out mingw
when we define _BSDTYPES_DEFINED.

Not quite ready to support pkg-config yet but go ahead and provide
basic support in configure to discourage distributions that are
patching pkg-config support in to no longer run "autoreconf -f"
and wiping out our custom libtool. sane-backends.pc will not
be installed currently.
Also, fixed a LDFLAGS bug in sane-config for GPHOTO2 support.

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.

Allow user to configure support for rpath compiler
option. Ported from Fedora's sane-backend patches.
