[nielsdos]

It's not only redefinitions, but also warnings about initializers I see.
You're using gcc 4.2 that's from 2008. We had a couple of similar issues with very old gcc versions. See e.g. #14497
What's the reason you're using such an outdated compiler? Is it possible to use a more modern compiler?

[NattyNarwhal]

4.2 is the last GCC Apple shipped back then, but I’m pretty sure most ports systems on Mac provide a newer gcc.

[barracuda156]

@nielsdos @NattyNarwhal If it is not buildable anymore with Xcode gcc, we can use a newer one, I believe.

@ryandesign Ryan, should we just switch the port away from using archaic compilers?
