If hoard data is not initialized, hoard_resources_type::reset frees
GameBitmaps[0].data, which is bogus_data instead of nullptr or a valid
pointer.

gcc-4.6 fails to synthesize a move constructor to initialize
reversed_render_range; later gcc accept this.
Switch to capturing the value by const auto &&, which works in both old
and new gcc.
gcc-4.6 chokes on implicitly converting vobjptridx_t to int/uint16_t;
later gcc accepts this. Cast the vobjptridx_t directly to short to
force gcc-4.6 to find the correct conversion operator.

gcc-4.6 chokes on casting vobjptridx_t to long; later gcc accepts this.
Change the format string to short, then switch the conversion to
objnum_t, which has an exact match for the converting operator.
gcc-4.6 chokes on constexpr operator int(); later gcc accepts this.
menu_fix_wrapper is never converted in constexpr context, so remove the
constexpr specifier.
