* sysdeps/generic/errno.c [! USE___THREAD]
[HAVE_ELF && SHARED && DO_VERSIONING] (errno, _errno): Declare these with compat_symbol so they are not link-time visible. [! USE___THREAD] (__libc_errno): New alias for errno. * csu/Versions [!(USE_TLS && HAVE___THREAD)] (libc: GLIBC_PRIVATE): Add __libc_errno here. * inet/herrno.c [USE___THREAD]: Use this conditional in place of [USE_TLS && HAVE___THREAD]. [! USE___THREAD] [HAVE_ELF && SHARED && DO_VERSIONING] (h_errno, _h_errno): Declare these with compat_symbol so they are not link-time visible. [! USE___THREAD] (__libc_h_errno): New alias for h_errno. * resolv/res_libc.c [! USE___THREAD] [HAVE_ELF && SHARED && DO_VERSIONING] (_res): Likewise. (_res): Use __attribute__ ((section (".bss"))) so we can have an alias. (__libc_res): Define as alias for _res. * resolv/Versions [!(USE_TLS && HAVE___THREAD)] (libc: GLIBC_PRIVATE): Add __libc_h_errno and __libc_res here. 2002-11-14 Jakub Jelinek <jakub@redhat.com> * csu/Versions (errno): Move STT_TLS symbol to GLIBC_PRIVATE for now. * resolv/Versions (h_errno, _res): Likewise. 2002-11-14 Roland McGrath <roland@redhat.com>
