Subject: bug#25623: CC Mode 5.32.99 (C/l); `c-defun-name' returns wrong result for filescope enums, structs and unions
Date: Sun, 05 Feb 2017 08:17:50 +0530

When the point is in struct, enum or union of file scope, `c-defun-name'
returns wrong result.

Eg: In the following example (where `|' is where the points are (ie, 3
cursors are 3 different cases),
case 1, in struct: the result is "t" ("struct test" may be a better
result, the same for union)
case 2, in enum: the result is "ONE" ("enum" may be better)
case 3, in main: the result is "main" (which is of course, right)

Also, simply return "struct", "union", etc if no tag name is present
(like in "typedef struct {...")

struct test
{
  int a;|
};

enum {
  ONE,
  TWO|
};

int
main (void)
{
  |
}


Thanks
