No I don't agree because that would cause an ABI change. Note some
targets (arm-eabi though not arm
Okay, I am sorry for not knowing that there is an option to make enum types as

With the three C++ compilers I tried enums are int-sized for
compatiblity reasons, so that enums declare

What do you think about making enum types have only the size needed for the
