Update.
2001-02-26 Ulrich Drepper <drepper@redhat.com> * dlfcn/Makefile (distribute): Add modatexit.c and modcxaatexit.c. (tests): Add tstatexit and tstcxaatexit. (module-names): Add modatexit and modcxaatexit. Add rules to build and run tstatexit and tstcxaatexit. * dlfcn/modatexit.c: New file. * dlfcn/modcxaatexit.c: New file. * dlfcn/tstatexit.c: New file. * dlfcn/tstcxaatexit.c: New file. * io/Makefile: Pass -DHAVE_DOT_HIDDEN to stat and mknod functions if .hidden is available. * io/stat.c: If .hidden is available use it to avoid exporting functions. * io/fstat.c: Likewise. * io/lstat.c: Likewise. * io/stat64.c: Likewise. * io/fstat64.c: Likewise. * io/lstat64.c: Likewise. * sysdeps/generic/mknod.c: Likewise. * malloc/mtrace.c: Use __cxa_atexit and not atexit. * sysdeps/generic/bb_init_func.c: Likewise. * sysdeps/generic/libc-start.c: Likewise. * stdlib/atexit.c (__new_exitfn): Move to cxa_atexit.c. (atexit): Implement using __cxa_atexit. Use .hidden if availble to avoid exporting atexit. * stdlib/cxa_atexit.c (__new_exitfn): Moved to here from atexit.c. * stdlib/Versions: Export __new_exitfn for GLIBC_2.2.3. * stdlib/Makefile (routines): Add old_atexit. (static-only-routines): Add atexit. Pass -DHAVE_DOT_HIDDEN for atexit.c if .hidden is available. * stdlib/old_atexit.c: New file. * intl/Makefile: Remove bogus endif.
