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.
patches have been applied yet, but it's a start. The backends
are not installed as shared libs but as add-ons, which are shared libs
but in a specific folder in [/system|~]/config/add-ons/ named SANE/.
The install target has been changed to account for this,
Some files don't exist in BeOS/ZETA (ipc.h, ...).
Bbackend function names get a prefix, I suppose to avoid namespace clashes.
Though we do have a libdl to implement dl_open, the native way is prefered.
Added a --with-docdir= configure arg.
BeOS has a broken get[name|addr]info() from bind. This is fixed in ZETA R1.
libtool needs -no-undefined. Various VPATH fixes.
Check for <be/drivers/USB_scanner.h>, but not used yet.
No S_IFSOCK (sockets are fds to /dev/net/api). Stub pio code, untested.
Patch from Francois Revol <revol@free.fr>.
