Assuming this has been tested, LGTM

P. S. Title is inaccurate, it was not broken on 32-bit earlier :)

@aeiouaeiouaeiouaeiouaeiouaeiou While a non-functional matter, but IMO it will be still useful to have commit titles reflecting what is fixed more accurately.

Someone looking through history will assume it was broken on < 10.9 before, which is not strictly the case. What was broken is only one of 3 arches (or 2 of 4, if we assume ppc64 is buildable).

@barracuda156 that's why I added "refactor", let's see what the repository admins have to say about the solution.

@aeiouaeiouaeiouaeiouaeiouaeiou I would rather see ”fix 64-bit builds on < 10.9” (or smth to the same effect), but no big deal.

@barracuda156 oops, this commit was better because built binary from the packages server causes a segmentation error (MAC_OS_X_VERSION_MIN_REQUIRED should be in both parts of the code, but it was fine with the local test) :/

@aeiouaeiouaeiouaeiouaeiouaeiou I thought it is a fairly trivial change and did not compare patch versions, but locally it works fine, at least it starts without issues, I just tried.
