[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.
