Now endian.hpp defines BOOST_BIG_ENDIAN on HP-UX.
This was suggested by Boris Gubenko.

If you are right John, then this seems to be incorrect.
Shouldn't endian.hpp then define something like BOOST_UNKNOWN_ENDIAN on 
HP-UX?

Boris, do you have any comments on this?

Then my fpclassify could use a fast implementation when BOOST_BIG_ENDIAN 
or BOOST_LITTLE_ENDIAN is defined and a slower implementation when 
BOOST_UNKNOWN_ENDIAN is defined.
