[cfe-dev] [Windows toolchain] link failures from command prompt

I just filed a bug report (http://llvm.org/bugs/show_bug.cgi?id=17428)
against LLVM-3.4.r191323-win32.exe. Here is the rationale for considering
failure to link under the "Developer Command Prompt for VS2012" a bug:
Boost developers and test runners, and probably lots of other folks too, run
their automated tests from the command prompt rather than via the IDE. So it
is a showstopper for these folks if the clang windows toolchain doesn't work
from the command prompt.
In my little hello.cpp test the clang++ compile was clean, but the link had
unresolved externals like "hello-111ee3.o : error LNK2019: unresolved
external symbol __ZSt4cout referenced in function _main".
That's particularly frustrating since it is so close to working!
Once the command prompt is working, I'll submit a patch to
http://llvm.org/builds/ explaining how to use it.
