And my Linux machines have byteswap.h, which does 64 bit, too. However I 
guess, these aren't too portable. I can think of a wrapper header file 
which encapsulates the functionality in some easy-to-use macros. The 
implementation checks for bswap_xx functions (in byteswap.h), if not 
found then {h|n}toxx functions (in netinet/in.h or something that the 
BSD folks likes, too), and if neither present implement these with some 
custom code. Or any better idea?
