------- Additional Comments From papadopo at shfj dot cea dot fr 2005-05-30 09:35 -------
In the 64-bit case, again none of BYTE_ORDER, BIG_ENDIAN or LITTLE_ENDIAN are
defined. As far as I can understand, the configure script stops there and
doesn't run additional tests as in the 32-bit case.
Is there anything else I can test?
$ cat > conftest.c
main () {
/* Are we little or big endian? From Harbison&Steele. */
union
{
long l;
char c[sizeof (long)];
} u;
u.l = 1;
exit (u.c[sizeof (long) - 1] == 1);
}
