Subject: Check __BIG_ENDIAN__ and __LITTLE_ENDIAN__ to determine endianness.
X-Git-Tag: krb5-1.8-alpha1~355
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=66f4ea3db7a9c1eb278b035fdae8ebea7636edb9;p=krb5.git

Check __BIG_ENDIAN__ and __LITTLE_ENDIAN__ to determine endianness.
In fallback code, check ia64 platforms for hpux vs everything else;
HP-UX uses big-endian mode.

ticket: 6565
