I wrote the Perl bindings for Sane based on 1.0.19, on the basis that until the API changed, they would build properly, even if new symbols weren't supported until I added the support.
However, on a rebuild of sid, which has 1.0.20, libsane-perl FTBFS, as SANE_CAP_ALWAYS_SETTABLE has been removed (http://git.debian.org/?p=sane/sane-backends.git;a=commit;h=e91fea4ac1ced39c911db91489c7069784bea037) So - a. doesn't removing SANE_CAP_ALWAYS_SETTABLE change the API? b. are there any backends in 1.0.19 that use SANE_CAP_ALWAYS_SETTABLE?
