Seems to me the way to handle this is to call out to another function
to do the actual fp i/o.  Since we're talking about vfprintf, an interface
as simple as

  void do_fp_printf(FILE *f, int width, int prec, char fmt, va_list *arg)

should cover all the cases.  It is also now easy to ifdef it out, which
could be nice for the embedded folks.
