aloha ralph and interested saners

gitlab will not allow me to even view the site -- it pops up
a message 'your browser is too old ...'

that is something i'm used to with this here prehistoric
system.  unfortunately i'm using the most recent (ancient)
firefox browser available, so gitlab and me are a no go.
i'm so glad the sane webmaster finally put tarballs of various
newer releases on the sane-project.org webpage -- thanks.

i can provide the build log if you want plus the very
few diffs i had to make to get 1.0.32 withe the sun libusb
legacy version to build.  just let me know where to send it.

details: i had -Wall on so lots of outputs -- complete log
of a distclean configure with compile of genesys sane-backend
is 700k and the config.log is nearly 625k.  i can compress
with most compressors if you request.  xz compresses tarball
with these two files to less than 50k.

diffs: 4 files mostly just conditional compilation directives
./testsuite/sanei/sanei_usb_test.c
./tools/sane-find-scanner.c
./sanei/sanei_usb.c
./sanei/sanei_scsi.c

NB: i've not changed any genesys source [yet] for 1.0.32, but
for 1.0.28 i only needed to correct variable types for a couple
of math library functions -- not used in new 1.0.32 genesys.

plus a post configure hack of ./include/sane/config.h
to correctly set HAVE_LIBUSB_LEGACY -- i've yet to
figure out what to change in configure.ac et-al to
do that automatically [at least for 1.0.32].

let me know if and how to proceed

thanks so much
