Alan Modra 1b6adf888d PowerPC floating point little-endian [1 of 15] 
http://sourceware.org/ml/libc-alpha/2013-08/msg00081.html

This is the first of a series of patches to ban ieee854_long_double
and the ieee854_long_double macros when using IBM long double.  union
ieee854_long_double just isn't correct for IBM long double, especially
when little-endian, and pretending it is OK has allowed a number of
bugs to remain undetected in sysdeps/ieee754/ldbl-128ibm/.

This changes the few places in generic code that use it.

	* stdio-common/printf_size.c (__printf_size): Don't use
	union ieee854_long_double in fpnum union.
	* stdio-common/printf_fphex.c (__printf_fphex): Likewise.  Use
	signbit macro to retrieve sign from long double.
	* stdio-common/printf_fp.c (___printf_fp): Use signbit macro to
	retrieve sign from long double.
	* sysdeps/ieee754/ldbl-128ibm/printf_fphex.c: Adjust for fpnum change.
	* sysdeps/ieee754/ldbl-128/printf_fphex.c: Likewise.
	* sysdeps/ieee754/ldbl-96/printf_fphex.c: Likewise.
	* sysdeps/x86_64/fpu/printf_fphex.c: Likewise.
	* math/test-misc.c (main): Don't use union ieee854_long_double.
