If we did this, we'd have to comply with POSIX namespace rules for
"feature macros".  However, I prefer the "better function in libm"
solution, since not everyone #include's stdio.h just to get printf.

This is one of the proposed solutions.  libc's printf will still
support long doubles, but will simply cast them to double and use the
existing double code.
