            Bug ID: 127394
           Summary: Incorrect warning for nodiscard with enum type
                    specifier
           Product: gcc
           Version: 17.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: luigighiron at gmail dot com
  Target Milestone: ---

The following code incorrectly generates a -Wattributes warning:

enum[[nodiscard]]E:int{e};

If the enum type specifier :int is removed, no warning is generated. No warning
is generated when compiling in C++ instead.
