2018-01-11 Michael Meissner <meissner@linux.vnet.ibm.com>
* configure.ac (--with-long-double-format): Add support for the
configuration option to change the default long double format on
PowerPC systems.
* config.gcc (powerpc*-linux*-*): Likewise.
* configure: Regenerate.
* config/rs6000/rs6000-c.c (rs6000_cpu_cpp_builtins): If long
double is IEEE, define __KC__ and __KF__ to allow floatn.h to be
used without modification.
