That looks fairly bogus.

Please run

avr-g++ -g -Wall -fno-exceptions -Os -mmcu=at90s8515    -E main.c

and lookup what the preprocessor makes out of all this.  I can't see
how the above could happen with either rev 1.5 or 1.6 of avr/sleep.h.
Both first test whether SM0/SM1/SM2 are defined, and if they aren't,
the logic to use SLEEP_TYPE 1 should work.
