Just a sanity check, something like this was fixed mid-November in r195168:

   http://llvm.org/bugs/show_bug.cgi?id=17403

Are you using a recent clang SVN revision?

There's an additional bug report describing the full set of flags you 
may need to use (/GR- /D_HAS_EXCEPTIONS=0 /MTd) with current SVN head:

   http://llvm.org/bugs/show_bug.cgi?id=18332

Let us know if this works for you.
