Update.
2003-09-04 Ulrich Drepper <drepper@redhat.com> * libio/libio.h: Define _IO_FLAGS2_NOTCANCEL. * libio/fileops.c [_LIBC]: Remove close macro. (_IO_file_open): If _IO_FLAGS2_NOTCANCEL is set, use open_not_cancel. (_IO_new_file_open): Recognize 'c' flag in mode string. (_IO_file_read): If _IO_FLAGS2_NOTCANCEL is set use read_not_cancel. (_IO_new_file_write): If _IO_FLAGS2_NOTCANCEL is set use write_not_cancel. * iconv/gconv_conf.c: Use fopen with 'c' mode flag. * inet/rcmd.c: Likewise. * inet/ruserpass.c: Likewise. * intl/localealias.c: Likewise. * malloc/mtrace.c: Likewise. * misc/getpass.c: Likewise. * misc/getttyent.c: Likewise. * misc/mntent_r.c: Likewise. * misc/getusershell.c: Likewise. * nss/nsswitch.c: Likewise. * resolv/res_hconf.c: Likewise. * resolv/res_init.c: Likewise. * sysdeps/unix/sysv/linux/getsysstats.c: Likewise. * time/getdate.c: Likewise. * time/tzfile.c: Likewise. * misc/fstab.h: Undo last change. * misc/mntent.h: Likewise. * misc/Makefile: Remove CFLAGS-mntent_r.c, CFLAGS-mntent.c, and CFLAGS-fstab.c definition. 2003-09-04 Jakub Jelinek <jakub@redhat.com> 2003-09-03 Ulrich Drepper <drepper@redhat.com>
