I guess the cleanest way would be to memcpy the double (why is there even a 
typedef to data_64 for that...) to a unsigned char[8], do all the 
byteswapping on that, and memcpy it back later... apparently the original 
author thought this piece of code would be a bottleneck or something, so I'm 
not sure how much slower that would be.
