After running configure, can you look at the file include/sane/config.h?
Check if HAVE_GETOPT_H and HAVE_GETOPT_LONG are defined.   On debian, I
would expect them to be defined.  In that case, it uses standard libc
version of getopt.

I do see one suspicious line in lib/getopt.c and lib/getopt1.c.  They do a
#include <config.h> instead of #include "../include/sane/config.h" and so in
certain cases it may be including the wrong config.h file.  In that case, it
would mistakenly compile a conflicting version of getopt_long() (which can
explain the problem your seeing).
