I found a minor patch by Firefox to solve this namespace collision. So 
for whatever reason Apple's did differently, it now compiles on all 
compilers.

However clang9 generates a crashing executable. I tried on both 10.11 
and 10.13.

- Apple clang: works fine
- MacPorts clang 7: compiles & works
- MacPorts clang 9 : compiles but fails

anybody has seen this behaviour in other software, perhaps smaller and 
easier to test than ArcticFox?
