Oh wait sorry, that doesn't solve it (yet), the variant_storage_byte would
still have a default copy constructor that copies the byte member.

Hey,
Does this idea help: https://godbolt.org/g/3Iqp2c ?
The storage is an array of "special" byte classes which have empty
constructors/assign when those would be implemented by one of the mixins.

Presumably because std::variant is not trivially copy constructible,
the ABI will be unable to pass it by value in a register in a call

When indexing an array, gcc will sometimes perform a multiplication using
shifts and adds, instead of using the more efficient multiplication
instructions. This program demonstrates the issue

I've been reading the discussion there, but I don't see any interaction
problems with templates. Most of it is just useless arguing about whether fixed
point types can be implemented externally with templates.

As of version 4.8, GCC supports fixed point types for the AVR target. See:
http://gcc.gnu.org/wiki/avr-gcc#Fixed-Point_Support
However, this is only available in C and not in C++. Please
