```
$ cat /tmp/foo.c
struct foo {
        time_t mytime; /* missing <time.h> include should trigger fixit */
}

$ gcc /tmp/foo.c
foo.c:2:9: error: unknown type name 'time_t'
    2 |         time_t mytime; /* missing <time.h> include should trigger f=
ixit
*/
      |         ^~~~~~
foo.c:3:1: error: expected identifier or '(' at end of input
    3 | }
      | ^
```

Expected output is a <time.h> "fixit" like:
```
test.c:3:13: error: unknown type name 'time_t'
    3 | void myfunc(time_t test) {
      |             ^~~~~~
test.c:2:1: note: 'time_t' is defined in header '<time.h>'; did you forget =
to
'#include <time.h>'?
    1 | #include <stdio.h>
  +++ |+#include <time.h>
    2 |
