2004-10-14 Ulrich Drepper <drepper@redhat.com> * nscd/connections.c (nscd_init): Remove file if not persistent and not shared. Patch by Jerome Borsboom <j.borsboom@erasmusmc.nl>. * sysdeps/unix/sysv/linux/i386/setresuid.c: Handle defined __NR_setresuid32 && !defined __NR_setresuid. * sysdeps/unix/sysv/linux/i386/setresgid.c: Handle defined __NR_setresgid32 && !defined __NR_setresgid. * sysdeps/sparc/fpu/bits/mathinline.h (__signbitf, __signbit, __signbitl, sqrtf, sqrt, sqrtl, fdim, fdimf): Use __NTH macro. * sysdeps/generic/errno-loc.c: Don't undef #errno if RTLD_PRIVATE_ERRNO. * include/errno.h (__errno_location): If RTLD_PRIVATE_ERRNO, add attribute_hidden. * dlfcn/dlinfo.c (dlinfo_doit): Replace iteration over GL(dl_loaded) chain with iteration over all namespaces' _ns_loaded chains. * sysdeps/powerpc/powerpc32/dl-machine.c (__elf_preferred_address): Likewise. * sysdeps/mips/dl-machine.h (elf_machine_runtime_link_map): Likewise.
