--- Comment #5 from Paolo Carlini <paolo.carlini at oracle dot com> 2012-10-09 11:28:45 UTC --- Ok, thanks, I missed that remark of yours. Well, at present nothing prevents people with big endian machines to try to use the code, and we unconditionally run the testsuite. That's not Ok. Let's keep the PR open for a while in case somebody wants to try your suggestion, otherwise, as far as I'm concerned, for 4.8.0, I will just disable the code and its tests on big endian.
