Close, but no cigar.  It is true that in the abscence of prototype information,
a compiler conforming to X3J11 has to convert float to double on calls (but
is allowed to use single precision in expressions).  However, if you have a
prototype in scope, the compiler is not obligated to convert to double
precision.
