Updated patch without offending ()'s
2006-04-07 Steven Munroe <sjmunroe@us.ibm.com>
* sysdeps/powerpc/fpu/bits/mathinline.h
[__WORDSIZE == 64 || _ARCH_PWR4]: Define __CPU_HAS_FSQRT.
(__ieee754_sqrt): Fix comment.
(__ieee754_sqrtf): Fix comment.
* sysdeps/powerpc/fpu/e_sqrt.c (__ieee754_sqrt): Fix comment.
Check __CPU_HAS_FSQRT instead of dl_hwcap.
* sysdeps/powerpc/fpu/e_sqrtf.c (__ieee754_sqrtf): Fix comment.
Check __CPU_HAS_FSQRT instead of dl_hwcap.
