I think this might be a good time to look at making the switch, there
are a number of other benefits from doing so, such as access to a
range of compilers, better support for C++ exceptions, etc.
AAPCS has short-enums but it seems we can say we don't use them with
Instead of assigning enumeration containers as described above, a
virtual platform may elect to use word-sized containers (int and
unsigned int) for all enumeration types. In this case, the container
type is int unless the upper bound is greater than 2147483647. A
platform standard must document its choice.
