Sometimes, even on AVR there is the need to align data.
However, alignments of 2 are ignored at the moment because of
#define ASM_OUTPUT_ALIGN(STREAM, POWER) \
do { \
if ((POWER) 1)\
fprintf (STREAM, \t.p2align\t%d\n, POWER); \
} while (0)
The fix is to use POWER 0 instead.
Maybe someone knows why the restriction to POWER = 2 is
there at all?
Ok to install?
