Exactly and gcc for arm uses this definition to its advantage so that it can
save some size.

GCC can smartly chose type based on enum values for size reasons and it will
choose the smallest type that can represent the enum. In this testcase enum can
be represented by a char.
with
__extension__ enum tree_code code:16
The testcase is asking for the bit-fields which are not defined for the enum
type that gcc has chosen So I think error is ok here.
