[phobos] Phobos trunk seems to not build for OSX

[Andrei Alexandrescu]

I'm saying "seems" because I'm not 100% clear that I have the latest and 
greatest. On the master branch I did:

git merge origin/master

and got a bunch of changes. Now when I try to build unittest I get:

std/datetime.d(28538): Error: undefined identifier tzname, did you mean 
function name?

Could someone confirm?
