How about this, then:  correct C preprocessors replace comments with white
space.  The Reiser cpp was *broken*, and many, many other implementations
existed that did not do that.

I can think of about 30.  Ok, an exaggeration, but I can name at least 5 or
6 that did not do this.

You can cast an lvalue.  However, the result is no longer an lvalue.  What
is a compiler supposed to make of:

	int f;
	(float)f++;

Learn the language.
