[sane-devel] adding a define to sane.h

[stef]

        Hello,

        there is a SANE_CURRENT_MAJOR defined. To ease the compilation of 
frontends 
outside SANE tree, how about adding a SANE_CURRENT_MINOR define ? Fronted 
could then handle compiling against SANE 1.0 or SANE 1.1

Regards,
        Stef
