I see 16 on Linux/x86-64.

I think you mean "%Lf" (or "%Lg" or "%Le").
Incidentally, there's a workaround for MinGW's long double bug. If you
define the macro __USE_MINGW_ANSI_STDIO as 1 before including <stdio.h>,
it will use its own implementation of printf rather than MSVCRT. (I
don't know whether that also fixes problems with the long double math
functions.)
