* - Define BIGENDIAN on big-endian systems. Untested, as all target
* systems to date are little-endian.
* - Define ALIGNMENT_WORKAROUND if your system doesn't support
* non-aligned memory access. In this case, we use a slower, but safer,
* memory access method. This should be done automatically in config.h
