   Status:  new                                                |   Milestone:  Boost 1.36.0
Component:  None                                               |     Version:  Boost 1.35.0
 Severity:  Problem                                            |    Keywords:

 In <boost/detail/endian.hpp>:
 {{{
 #elif defined(_BIG_ENDIAN)
 # define BOOST_BIG_ENDIAN
 # define BOOST_BYTE_ORDER 4321
 #elif defined(_LITTLE_ENDIAN)
 # define BOOST_LITTLE_ENDIAN
 # define BOOST_BYTE_ORDER 1234
 }}}
 But, the system header <sys/endian.h> on NetBSD always defines
 _LITTLE_ENDIAN, _BIG_ENDIAN and _PDP_ENDIAN.
 So BOOST_BIG_ENDIAN is defined on little endian platforms.


 Please change it as follow:
 {{{
 #elif defined(_BIG_ENDIAN) && !defined(_LITTLE_ENDIAN)
 # define BOOST_BIG_ENDIAN
 # define BOOST_BYTE_ORDER 4321
 #elif defined(_LITTLE_ENDIAN) && !defined(_BIG_ENDIAN)
 # define BOOST_LITTLE_ENDIAN
 # define BOOST_BYTE_ORDER 1234
 }}}
