Not Working on the Mac

[Walter Bright]

This problem:

https://www.digitalmars.com/d/archives/digitalmars/D/D_has_become_unbearable_and_it_needs_to_stop_369162.html#N369573

was apparently fixed on LDC:

https://forum.dlang.org/post/himxshnmnapmyipsvqlq@forum.dlang.org

with this PR:

https://github.com/ldc-developers/ldc/pull/3868/files

I don't understand the internals of LDC, and would appreciate it if someone took 
this in hand and developed the equivalent in DMD.

Thanks!
