C++98 is stricter than C90 about integer constants.  _Explicitly_ using
long long is one thing (accepted as an extension by the C++ compiler),
_implicitly_ using it (by having too large an integer constant without a
suffix) is another.  The behaviour may or may not be as intended; that's
for the C++ maintainers to work out.
