The C/C++ standard header names are defined by the standards, and  
cannot be changed because of that (and need not even be implemented  
as files). For else, I don't know whether this is a GNU rule, but  
Bison uses it. For awhile, I experimented with none, as in the C++  
standard libraries, but the practical problems is to get file types  
recognized by various programs. And ".h" is a C header file, the  
latter which is a  language different from C++. So, using ".hh" might  
be a good idea after all - I am switching to it myself now.
