* nis/Makefile (libnsl-routimes): Add nss-default.
* nis/Versions (libnsl) [GLIBC_PRIVATE]: Export _nsl_default_nss. * nis/nss-nis.c: Move /etc/default/nss handling to... * nis/nss-default.c: ...here. New file. * nis/libnsl.h: New file. * nis/nss-nis.h: Remove NSS_FLAG_* definitions and _nis_default_nss plus auxilary definitions. * nis/nss_nis/nis-initgroups.c: Use _nsl_default_nss instead of _nis_default_nss. * nis/nss_nis/nis-service.c: Likewise. 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): Likewise.
