- NaN functions: getpayload, getpayloadf, getpayloadl, setpayload,
setpayloadf, setpayloadl.
* The functions strfromd, strfromf, and strfroml, from ISO/IEC TS 18661-1:2014,
are added to libc. They convert a floating-point number into string.
* On ColdFire, MicroBlaze, Nios II and SH3, the float_t type is now defined
to float instead of double. This does not affect the ABI of any libraries
that are part of the GNU C Library, but may affect the ABI of other
libraries that use this type in their interfaces.
* The functions strfromd, strfromf, and strfroml, from ISO/IEC TS 18661-1:2014,
are added to libc. They convert a floating-point number into string.
* On x86_64, when compiling with -mfpmath=387 or -mfpmath=sse+387, the
float_t and double_t types are now defined to long double instead of float
and double. These options are not the default, and this does not affect
the ABI of any libraries that are part of the GNU C Library, but it may
affect the ABI of other libraries that use this type in their interfaces,
if they are compiled or used with those options.
* The <sys/quota.h> header now includes the <linux/quota.h> header. Support
for the Linux quota interface which predates kernel version 2.4.22 has
