[cfe-dev] Clang++/MSVC10 chokes on "__unaligned" in VS header files

[Ruben Van Boxem]

Hi,

I built LLVM/Clang with MSVC 10.0 and tried to compile a little
program using std::vector.

A google search shows clang/lib/CodeGen/MicrosoftCXXABI.cpp
knows/should know about __unaligned, or at least this part of Clang
knows about it.

Anything I can do? Thanks!
