The 3.4 release for Windows doesn't support Windows XP. Unfortunately
we didn't realize this until after the release.

The good news is that the more recent versions of the snapshots at
http://www.llvm.org/builds/ are built with XP support.

stdio.h isn't included because we don't provide a C standard library.
You'll have to use the standard library from Visual Studio or MinGW.

Hope this helps,
