     If you use `#pragma implementation' with no argument, it applies to
     an include file with the same basename(1) as your source file.
     For example, in `allclass.cc', giving just `#pragma implementation'
     by itself is equivalent to `#pragma implementation "allclass.h"'.

I'm not saying you have to change your source -- I just want to
understand what's happening.
