The problem is that bswap_{16,32,64}() and the existence of
<byteswap.h> is not guaranted by any standard that I'm not aware of.
A quick Google search indicates that it's not available for the
following platforms:
* Mac OS X 10.5
* FreeBSD 6.0
* NetBSD 5.0
* OpenBSD 3.8
* Minix 3.1.8
* AIX 5.1
* HP-UX 11
* IRIX 6.5
* OSF/1 5.1
* Solaris 11 2011-11
* Cygwin
* mingw
* MSVC 9
* Interix 3.5
* BeOS
So the only way we could use bswap_{16,32,64} if there is a proper
configure.in test for them.
