In the format string for *scanf functions, the '%as', '%aS', and '%a[]' modifiers behave differently depending on ISO C99 compatibility. When _GNU_SOURCE is defined and -std=c89 is passed to the compiler, these functions behave like ascanf, and the modifiers allocate memory for the output. Otherwise, the ISO C99 compliant version of these functions is used, and the modifiers consume a floating-point argument. This patch adds the IEEE binary128 variant of ISO C99 compliant functions for the third long double format on powerpc64le. Tested for powerpc64le. Reviewed-by: Paul E. Murphy <murphyp@linux.ibm.com>
