Trouble complinig DMD 2.070 on windows

[E.S. Quinn via Digitalmars-d]

I'm trying to compile a 64-bit DMD.exe on windows (as my project 
has enough CTFE and Template work that it bumps up against the 
4gb limit).

with the pre-DDMD setup I was just able to load the thing up in 
visual studio 2013 and build, but I've been having some 
difficulty with 2.070's projects. Namely, it seems that no matter 
what type of bulid I do, I get a bunch of errors in elfobj.c and 
one in filename.d

(If this is an actual issue with the code or projects I'll file a 
bug, but I wanted to make sure it wasn't just me doing something 
wrong first)
