To this, I should have asked Chris to add:--

 - Microsoft's convention of printing at least three exponent digits,
   for "%e" format, (and for "%g" when appropriate), is retained as
   default; support for _set_output_format(_TWO_EXPONENT_DIGITS) is
   included, for users of MSVCR80.DLL (and later).

 - Users preferring the ISO-C99/POSIX standard of only two exponent
   digits may set PRINTF_EXPONENT_DIGITS=2, in the environment; this
   capability is supported by all of the MinGW replacement functions
   named above, for users of all versions of MSVCRT.

Keith.
