These constants are ultimately defined in 
llvm/include/Support/DataTypes.h.  This file is included by Constants.h, 
which is included by Constants.cpp.

The DataTypes.h header file is generated by the configure script and 
placed into your build tree.  My best guess is that your system's header 
files do not correctly define these macros, so they are missing.

Apparently, the MicroSoft compilers have the same problem.  You might 
want to change the #ifdef guards in DataTypes.h so that all the stuff 
that is defined when _MSC_VER is defined is also defined on your system.

You're building on Interix, right?

Please let us know if you run into any more problems.
