[BZ #6845]
2008-08-14 Ryan S. Arnold <rsa@us.ibm.com>
[BZ #6845]
* sysdeps/powerpc/fpu/bits/mathinline.h (__signbitl): Copy new
__signbitl definition and __LONG_DOUBLE_128__ guard from:
* sysdeps/unix/sysv/linux/powerpc/bits/mathinline.h: Remove as
redundant. Functions which call floating point assembler operations
should go into a sysdeps powerpc/fpu directory.
