Details:

The _MemoryBarrier() macro defined in avr/cpufunc.h results in the following
error when compiling:
error: expected string literal before ':' token

Currently defined as:
#define _MemoryBarrier() __asm__ __volatile__(:::"memory")

Should be:
#define _MemoryBarrier() __asm__ __volatile__("":::"memory")
