source: trunk/gsdl3/src/packages/mg/lib/netorder.h@ 10840

Last change on this file since 10840 was 10840, checked in by kjdon, 18 years ago

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
