error: 'NULL' was not declared in this scope (SourceLocation.h:212)

Hello,
After SVN update to r44952 I have the following compilation error:

make[1]: Entering directory
`/data/ngi/ebastien/llvm-SVN/llvm/tools/clang/Basic'
llvm[1]: Compiling Diagnostic.cpp for Release build

It was fine with r44790.

It should now be fixed. Let me know if you still have problems.
