Comment (by kencu):

 and now that we have a custom libc++, it will be interesting to see if the
 current mame will be able to use it to build on all systems...

 {{{
 # support. That's only supported by MacOS system libc++ from 10.13 onward.
 # However, once MacPorts provides a custom libc++ for all ports, Mame will
 # support older MacOS releases.
