As do I.  GCC refers to _TINY_ as _PATCHLEVEL, see below.

Yes.

#ifdef __GNUC__

#define __GCC_VERSION__ (__GNUC__ * 10000 \
                               + __GNUC_MINOR__ * 100 \
                               + __GNUC_PATCHLEVEL__)

/* Test for GCC < 3.4.0 */
#if __GCC_VERSION__ < 30400
#include <avr/ina90.h>
#endif

/* Test for GCC >= 3.4.3 */
#if __GCC_VERSION__ >= 30403
#include <compat/ina90.h>

#endif /* #ifdef __GNUC__ */
