The C++ compiler in use is now detected; vendor-specific compiler flags are now supported for C++ files. C++ file's output now also depends on the compiler (so if you update the compiler, everything will be rebuilt) and on the exact command line used to build it; this, together with the fact that $CXXFLAGS is used in the command line, means that changing that environment variable prompts a rebuild. At some point in the future I'll probably introduce a mode that fixes the contents of CXXFLAGS from the first build that happens for an output directory, plus some additional caching (like not having to respecify the compiler via CXX), but it's not a priority right now.

Also the dependency on the compiler isn't only on the exact path that is used, but also on all the symlinks along the way. I wonder whether this same approach should also be used for other dependencies, but let's ignore this for now.
