The code does build on MacOS X 10.6 when building for python.org's 64-bit python (thus using a newer compiler).

@r-owen Oooops! My bad. @mdboom's suggestion should fix it.

@mdboom Would you mind putting in a pull request for this?

[dmcdougall]

@mdboom Nevermind, I just did it.

Relevant PR is #1305.

[dmcdougall]

Fixed by #1305.
