          Issue ID: 22333
           Summary: ImportC: fails to parse enumerators with = and gnu
                    attributes
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nob...@puremagic.com

An example: 

// enum.c
enum E {
  oldval __attribute__((deprecated)) = 0,
  newval
};

int
fn (void)
{
  return oldval;
}

enum.c(3): Error: found `=` when expecting `}`
enum.c(3): Error: identifier or `(` expected
enum.c(5): Error: `=`, `;` or `,` expected

macOS’s version of time.h uses this.
