BYTE_SWAP is NOT defined on my Solaris 2.6 sparc system.

It might be useful to check if BYTE_ORDER and LITTLE_ENDIAN are
defined before seeing if they are not the same... On Solaris,
__BYTE_ORDER__ and __LITTLE_ENDIAN__ and __BIG_ENDIAN__ are defined in
/usr/local/gcc-2.7.2.3/lib/gcc-lib/sparc-sun-solaris2.6/2.7.2.3/include/sys/byteorder.h

Something like this patch seems to work for me. It might be better to
do something in config.h and test it with configure...

Note that the /usr/include/sys/byteorder.h file does not define either
BYTE_ORDER or LITTLE_ENDIAN or __BYTE_ORDER__ or __LITTLE_ENDIAN__ but
instead references _BIG_ENDIAN and other .h files reference _LITTLE_ENDIAN
even though I do not see a #define for any of them.
