New description:

 Mame 0.227 is failing to build on our infrastructure, with the combination
 of macOS 10.13 and Xcode 9.4.1. That's due to the use of C++
 aligned_alloc.

 However, builds succeed on macOS 10.13, when using Xcode 10.1.

 Note that Mame is utilizing macports-clang-9 for compilation, which
 supports aligned_alloc. So I suspect the macOS SDK provided by Xcode is
 the culprit.

 Presently investigating whether there is a fix for Xcode 9.4.1.
