• Daniel Murphy (2/11) Aug 23 2015 It should work, please file in bugzilla.

Let's say I have some C headers that have code like this in:

extern struct UndeclaredStruct blah;
Undeclared *p = &blah;

which would naïvely translate to D as:

struct UndeclaredStruct;
extern UndeclaredStruct blah;
auto p = &blah;

which doesn't compile. Why not? Neither the size nor any default 
initialiser is needed.

Yeah; workaround (plus mangling and TLS fix):

   struct UndeclaredStruct {}
   extern extern (C) __gshared UndeclaredStruct blah;
   auto p = &blah;
