It is consistent, GCC does not warm for this - but that was not the primary motivation in this case.

This is simply a convenience feature - considering that there are many C++ projects that use ".h" headers it saves the user from having to add "-xc++-header" in each case.

(since it is a convenience feature, it is non-essential, of course - but IMO useful even now)
