Comment:

 This fails to compile in recent clang with:
 {{{
 src/or/microdesc.c:85:14: error: no previous extern declaration for non-
 static
       variable 'outdated_dirserver_list'
 }}}

 {{{
 $ clang --version
 Apple LLVM version 9.0.0 (clang-900.0.38)
 Target: x86_64-apple-darwin16.7.0
 ...
 }}}

 (I have no idea what non-Apple clang version that corresponds to.)
