// whilst EABI attributes are being merged at link time unless
// the --no-enum-size-warning option is passed to the linker.  Whilst the
// enum-size attributes should only be emitted if there are values of
// enum type that can escape the compilation unit, gcc cannot currently
// detect this; if this facility is added then this linker option should
// not be needed.  arm-*-linux*eabi should be a good approximation to
// those platforms where the EABI supplement defines enum values to be
// 32 bits wide.
