The default argument promotions (C99 will convert
this float to double before the call.

However, I didn't see any #include <stdio.h> or int printf(const
char *format, ...) declaration in the source code posted to this
thread.  Calling a variadic function without a prototype results
in undefined behaviour in principle, but I don't remember whether
it matters in practice with the calling conventions of the Alpha.
