>Description:

The new cvs code comes with it's own md5 implementation (which IMHO should not
be used on NetBSD at all). This md5 always fails on sparc64 machines. At a
quick glance it looks like some broken ifdefs preventing the byteorder tests
to be reached, so the SWAP() macro ends up as a no-op. This would mean it's
broken on all big endian machines.

>How-To-Repeat:

run "cvs up" on a sparc64, note lots of "checksum failure after patch"
errors.

>Fix:
n/a
