GCC is correct warning about that, cause the Makefile asked for that
kind of warning. The buffer access is always aligned but the compiler
can't know that. To get rid of it, you would need to memcpy() the integer
in a variable or access it byte by byte and shift it to an integer
value. Removing -Wcast-align should be the easiest. :)
