2000-02-28 Ulrich Drepper <drepper@redhat.com> * sysdeps/unix/start.c: Initialize __errno and add comment explaining why. Remove K&R compatibility. * sysdeps/powerpc/fpu/s_isnan.c: Avoid using asm statement to declare aliases. * sysdeps/powerpc/Makefile: Always pass flags to compile for ppc and not rs6000. [$(subdir)=misc] (sysdep_routines): Add gprsave0, gprrest0, gprsave1 , and gprrest1. Don't pass special flags to compiler for init and gmon-start if this is no ELF platform. * sysdeps/mach/hurd/bits/statfs.h: Define _STATFS_F_NAMELEN. * sysdeps/unix/sysv/linux/bits/statfs.h: Likewise. * sysdeps/unix/sysv/linux/mips/bits/statfs.h: Likewise. * sysdeps/unix/sysv/linux/sparc/bits/statfs.h: Likewise. * sysdeps/posix/fpathconf.c: Don't unconditionally use f_namelen in statfs. Check feature macro and use f_name_max or NAME_MAX instead. * sysdeps/posix/pathconf.c: Likewise. * dlfcn/dlfcn.h: Remove DL_CALL_FCT definition here. * sysdeps/generic/bits/dlfcn.h: Define DL_CALL_FCT here. * sysdeps/mips/bits/dlfcn.h: Define DL_CALL_FCT here. * iconv/skeleton.c: If DL_CALL_FCT is not yet defined, add dumy definition here. * sysdeps/generic/libc-start.c: Fix typo in comment. * include/set-hooks.h: Allow systems to not define symbol_set_define. * configure.in: Unify machine names rs6000 and powerpc.
