            Bug ID: 61469
           Summary: language feature: Support for enum underlying type
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: nick87720z at gmail dot com

Just like some other features (inline functions, const, bool), ability to
specify data type for enumeration should be useful, since enumeration is just a
restriction for possible values.

Unlike C++, where type is specified as "enum class type ...", i propose
following forms:
- enum(type) ...
- type enum ...
