I don't think you need to do fancy #ifdef's:
static s32 return_eio_32(void) { return -EIO; }
static s64 return_eio_64(void) { return -EIO; }
extern void return_eio_unknown(void); /* Doesn't exist */
#define return_eio(type) ((sizeof(type) == 4) \
? ((void *) return_eio_32) \
: ((sizeof(type) == 8) \
? ((void *) return_eio_64) \
: ((void *) return_eio_unknown)))
