platform: Solaris 10 10/09 s10s_u8wos_08a SPARC
compiler: g++ (GCC) 4.9.0
scanner: canoscan lide200 (genesys gl847)
usblib: 0.1.7 (shipped with solaris)
notes: sane-backends 1.0.27 and sane-backends-master-e13b80fa built
and work so issue is with new c++ genesys implementation or
in other words my antiquated system and tools
i have tried -std=c++11, -std=c++14, -std=gnu++11 and -std=gnu++14 without
any change so either my c++ math headers are inadequate or i need additional
pow overloading declarations or ???.
i have also tried -D__EXTENSIONS__ with no change either.
these 3 errors seem to be the only ones being encountered at compile
time, but linkedit and runtime may reveal others ...

solutions other than get a more modern computer?
