I suppose that there is a bug already. http://savannah.nongnu.org/bugs/?37778.
Hope it gets fixed :-)
Thanks,

Subject: [avr-libc-dev] Bug in _MemoryBarrier()
Hi,
in my avr-libc there is a bug in avr/cpufunc.h in the memory barrier macro.
It is defined as
#define _MemoryBarrier() __asm__ __volatile__(:::"memory")
but should be:
#define _MemoryBarrier() __asm__ __volatile__("" :::"memory")
Best regards,
Martin Laabs
