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.
