One thing you've got to watch here is that the endianness of ints and 
pointers isn't necessarily the same as that for reals.

And just to throw a spanner in the works, I believe the Itanium can have 
it's endianness altered at runtime.  Whether any OS's will let you do that 
without crashing your program, I don't know, but I could certainly see uses 
for changing the endianness of reals at runtime (think big distributed 
applications, running over mixed hardware).
