I'd be happy to test the patch, thanks!

murmurhash3 test failures on big-endian systems

Ok, try the attached patch.  (It is a first pass at the issue, so it may not
be the final diff that'll end up getting committed.  It'd be good to
know if
it actually fixes the issue for you - sadly, I don't have a big endian
system to play with.)

Thanks,

Jeff.

Thanks for the quick response!

Unfortunately still fails, although with fewer assertion errors than 
before:

test-murmurhash3.c:34: Assert(#8) failed: memcmp(result, vectors[i].result,
sizeof(result)) == 0
test-murmurhash3.c:34: Assert(#11) failed: memcmp(result, vectors[i].result,
sizeof(result)) == 0
test-murmurhash3.c:34: Assert(#12) failed: memcmp(result, vectors[i].result,
sizeof(result)) == 0
murmurhash3 (murmurhash3_32) ......................................... : FAILED
test-murmurhash3.c:34: Assert(#12) failed: memcmp(result, vectors[i].result,
sizeof(result)) == 0
murmurhash3 (murmurhash3_128) ........................................ : FAILED

Regards,
Apollon
