Ok, an example:

#include <libio.h>
[
inside libio.h:
#define _IO_ferror_unlocked(fp) (((fp)->flags & _IO_ERR_SEEN) != 0)
]
....
....
....
#ifdef CONFIG_FOO
int flags;
#else
#define flags 0
#endif
...

	if (_IO_ferror_unlocked(stdio))  // cryptic error messags from gcc
		bad();


enum would work here just fine.
