delta-reduced input (not valid code but manages to make clang++ crash)

The following happens when colour_pretty_printer.cc is compiled with `clang++
-std=c++0x` and headers from libc++:

clang: DeclSpec.cpp:511: bool clang::DeclSpec::SetTypeSpecType(TST,
clang::SourceLocation, clang::SourceLocation, const char *&, unsigned int &,
ParsedType): Assertion `Rep && "no type provided!"' failed.

As a result of running multidelta, the attached file is not valid C++ code.

This is with clang version 3.0 git-1fba8281b9fab5bf11c4083e88f31047413f94f2.
