patch

The code for big-endian architectures is broken and doesn't compile.

#define fix_endian64(dst_, src_) dst_ = ethash_swap_u64(src_
misses ) at the end of line.

fix_endian_arr32 and fix_endian_arr64 are broken because of bad "while" placement. Unfortunately, I couldn't find what the issue is, so I just removed do while, which simplifies things.

Another error is that for loop in fix_endian_arr{32,64} uses , instead of ;.

Also remove const qualifier from nonce since it's actually modified and causes another build error (although Clang for some strange reason accepts it).

Tested on powerpc64 and amd64.

I have committed your patch with some modifications.

The problem is/was that there was a missing } before the while keyword. The reason for
the while is to enforce a ; after the macro call when using it.

Doh :(

It needed removing in just one place.

Have you submitted these patches upstream?

Thanks!
