[En-Nut-Discussion] WinAVR-20080512 -- same error as 20080411

[Thiago A. Corrêa]

Hi Ole,

   It seams avrlibc defines it as (my simplification):

/* Define internal _SLEEP_MODE_MASK that is no longer public in avrlibc. */
#ifndef _SLEEP_MODE_MASK
#if defined(SM) && !defined(SM0) && !defined(SM1) && !defined(SM2)

#define _SLEEP_MODE_MASK _BV(SM)

#elif !defined(SM) && defined(SM0) && defined(SM1) && !defined(SM2)

#define _SLEEP_MODE_MASK (_BV(SM0) | _BV(SM1))

#elif !defined(SM) && defined(SM0) && defined(SM1) && defined(SM2)

#define _SLEEP_MODE_MASK (_BV(SM0) | _BV(SM1) | _BV(SM2))

#endif
#endif


Perhaps we should use that instead in gcc.h
Looks like _SLEEP_MODE_MASK is still in avrlibc, excet that it's no
longer public. I guess the only clean solution would be to either push
for a get_sleep_mode in avrlibc mailling list or implement one
ourselfs.
