Update.
* sysdeps/unix/sysv/linux/tcgetattr.c (__tcgetattr): Fill in c_ispeed and c_ospeed fields. * sysdeps/unix/sysv/linux/speed.c (cfsetospeed): Set c_ospeed field. (cfsetispeed): Set c_ispeed field. * sysdeps/unix/sysv/linux/tcsetattr.c (IBAUD0): Define unconditionally to match corresponding speed.c code. 2003-09-06 Ulrich Drepper <drepper@redhat.com> * libio/wfileops.c (_IO_wfile_underflow): Mark beginning of the narrow character buffer. * libio/Makefile: Add rules to build and run bug-ftell. * libio/bug-ftell.c: New file. * stdio-common/vfprintf.c: Don't use the first grouping number twice. * stdio-common/vfscanf.c (vfscanf): Fix recognition of characters matching the decimal point and possibly leading the thousands separator. This caused the recognition of thousands separators to always fail. 2003-09-05 Ulrich Drepper <drepper@redhat.com> * libio/fileops.c (_IO_new_file_overflow): Handle switching to write mode from read in backup buffer. * libio/Makefile (tests): Add bug-ungetc2. * libio/bug-ungetc2.c: New file. 2003-09-05 Roland McGrath <roland@redhat.com> >>>>>>> 1.7905 * sysdeps/unix/sysv/linux/linux_fsinfo.h: Define VXFS_SUPER_MAGIC.
