These were intended to suppress GCC warnings about unused variables.
However, this leads to different warnings from Clang instead.
Use another approach that suppresses warnings from both compilers.
Backends use a mixture of SANE_CURRENT_{MAJOR | MINOR} and V_{MAJOR |
MINOR} with all kind of permutations. I was confused by this and one
comment in pieusb.c tells me I was not alone. Some items in old
changelogs suggest to use the SANE_CURRENT_ macros in backends, so let's
switch to do that with the exception of net.c and dll.c. Done with:
$ find backend -name '*.[ch]' | xargs sed -i '/nearly every/ ! { s/\<V_M/SANE_CURRENT_M/g }'
$ git checkout backend/net.c backend/dll.c
And manually removing the comment from pieusb.c. Everything still builds
fine.
With the exception of use in three quotes as well as our inlcuded copy
of the GPL, all use of the Free Software Foundation's postal address
has been removed.
Re #320.
at the end of the scan area and also missing parts of the scanned

package, based on Frank Zago's patches based on Adrian Perez Jorge's code. Fixed
compilation warnings. Fixed bug when no sane device was given. Code indented by
indent -gnu. Added man page.
