Hi,This patch fixes https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82307.For an unscoped enum with a fixed underlying type, the function type_promotes_to() does not always return the same type as the underlying type. The fix is to use the underlying type of the enum instead of creating a new one by calling c_common_type_for_size().Bootstrapped and tested with 'make check' on x86_64-linux. New test case added.Mukesh
