The rule for GNU projects is to, in the first hand, make sure that it  
is compatible with GCC; the rest is optional. In particular, it is  
important that one in C++ can use std::size_t without ::size_t, in  
order to avoid namespace clashes.

And I think that GNU favors giving C++ headers the filename extension  
".hh".
