Great, integration with VC++ will make a lot of people happy I think.
One note: under what license are the above pieces of code released? I ask, because
Win32 code seems to be released under a free license far less often than *nix
code.

If I remember correctly the Win32 API has a feature with which a process can
request a notification when a certain directory or file changes.

The emacs method is very simple: if you choose 'compile' under the tools menu,
emacs will run an external program (by default 'make -k').  It then puts the
output of this program in a separate buffer. This program (usually gcc or g++)
outputs it messages in the format '<filename>:<linenumber>: <message>'. Emacs
'knows' this simple format, so if you display the output buffer and click on one
of these lines, emacs will display the corrresponding file at the correct line.
That's all.

This would work with the Java test runner too.
