As was noted before, this is part of the default argument promotions
that C and C++ define as standard.  This is more explicit in the ANSI
C standard (search for "default argument promotions" in your favorite
ANSI C spec).  The C++ version handwaves a bit when it comes to the
float, int, and enum promotions but (I think) the behavior is the
same.
