See the GCC docs:
<http://gcc.gnu.org/onlinedocs/gcc-3.3/gcc/Code-Gen-
Options.html#Code%20Gen%20Options>

Look for -fpack-struct. This option is used in the WinAVR 
sample makefile. To not pack structures, remove this 
option, or alternatively use -fno-pack-struct.

Don't forget to consult the manual first.
