Actually there are properties on the source files to make this change
rather than forcing it... but, I do it because there are features that
compile better with C++.  Although C Compilers often give me a way to
hook into their runtime init (code that is run before main) it's
easier (and more standard) to implement static classes that do the same
deadstart initialization.

Although the code is C, renaming all the files to C++ isn't really proper.

Plus, the code will even compile with /CLR under visual studio and be
'managed', but that requires compilation as C++.
