When I try to build a library on Linux (Ares) and then link against that 
library, I get a bunch of link errors saying "undefined reference to 
'_ModuleInfo_3std1c6string'" and so on.  It appears this problem goes 
away if empty unittest blocks are added to all modules currently lacking 
unit tests, but this seems an odd fix.  I've tried building the library 
with a variety of switches for 'ar' but still see the problem.  Am I 
doing something wrong, or is this a DMD bug?  I can't find any 
significant differences in how my library is being built compared to how 
Phobos is built.  Does it actually matter that libphobos.a is built as a 
demendency of unittest.d?

unittest.d isn't the cause.
