glibc/libio
History
Joseph Myers 01d34e934a Add C2X _PRINTF_NAN_LEN_MAX 
C2X adds a macro _PRINTF_NAN_LEN_MAX to <stdio.h>, giving the maximum
length of printf output for a NaN.  glibc never includes an
n-char-sequence in its printf output for NaNs, so the correct value
for glibc is 4 ("-nan" or "-NAN"); define the macro accordingly.

This patch makes the macro definition conditional on __GLIBC_USE
(ISOC2X), as is generally done with features from new standard
versions.  The name is in the implementation namespace for older
standards, so it would also be possible to define it unconditionally.

Tested for x86_64.
