Changeset 10840

Message:

added check for endianness: AC_C_BIGENDIAN, which defines WORDS_BIGENDIAN to configure. Then netorder.h checks for WORDS_BIGENDIAN, rather than LITTLE_ENDIAN, _LITTLE_ENDIAN, LITTLE_ENDIAN etc, as these get defined on all platforms. This meant that linux collections would not work on teh mac because doubles were getting the wrong endianness
