 Replying to [comment:2 ryandesign]:
 > MacPorts uses libc++ by default on 10.6 and later. Are you sure that
 mame is using libstdc++? If it is, that is a bug that should be fixed; it
 should use the C++ stdlib that MacPorts tells it to.

 No, you're right... Mame is using libc++, rather than libstdc++. I wanted
 to log this ASAP, to ensure folks know I'm working these issues. But was
 clearly a bit too hasty. LOL

 As for the issue, I've built with both Clang 9 and 10 [the MacPorts
 versions], and it fails in both cases. So... does that mean the same
 issues exists in both Clang/LLVM 9, as well as 10... but only on MacOS
 10.8?
