The problem with making the cpp "know" the file to be included is already in scope is truly religious history: you can't be sure that some idiot trying to program C++ in C didn't define something, #include a file which ##'ed the something as a prefix/suffix, then redefined the thing, and included the same file again (think of "template classes for C" and you will get the -- nauseating -- picture). In addition, there are know dwiddley's (a dwiddley is someone who puts code in an include file).
