[cfe-dev] Win7 VS2008/2010 builds are broken

[John Wiegley]

Hello,

I'm building the current Git version using Windows 7 x64, and both Visual
Studio 2008 and 2010.  The commits I'm building are:

  LLVM  3ef750d
  Clang 822f54a

With Visual Studio 2008, Clang builds, but it fails 100 tests, all in the
"test/Index" directory.

With Visual Studio 2010, Clang fails to build with this error:

Build FAILED.

I'm posting this to see if others are aware of this problem, as it happened
sometime between today and July 22nd.

Thanks,
