* configure.ac (STAGE2_CFLAGS): Check if -fno-stack-protector is
supported by GCC. If yes, added the option. This is necessary
for OpenBSD, because the stack protector defines additional
symbols. Reported by uc.sheda <uc.sheda@laposte.net>.
* stage2/char_io.c [!GRUB_UTIL] (memcpy): New function. It is
defined as an alias of grub_memmove. This is copied from GRUB 2.
* stage2/disk_io.c (print_completions): Simplified conditionals
to make it easier to edit the file with Emacs.
Added support for (cd).
(set_device): Likewise.
* stage2/common.c (init_bios_info): Check if BOOT_DRIVE is a
CDROM drive. If it is true, set CDROM_DRIVE to BOOT_DRIVE.
(cdrom_drive): New variable.
From Leonid Lisovskiy <lly@pisem.net>:
* stage2/start_eltorito.S: New file.

Change the type of BUFADDR from int to char *.
Use a virtual track to make sure that one track fits in the
buffer.

a bios drive for a CD-ROM is often assigned to greater than
0x88.
(set_device): Use GRUB_INVALID_DRIVE instead of 0xFF.
(setup_part): Likewise.
* stage2/cmdline.c (init_cmdline): Use GRUB_INVALID_DRIVE.

if the drive is a CDROM.
(get_cdinfo): New function.
(get_diskinfo): Call get_cdinfo if the drive is greater than or
equal to 0x88 or the drive supports LBA.
Set the sector size to SECTOR_SIZE if it is not a CD-ROM.
* stage2/asm.S (biosdisk_int13_extensions): Take a word
argument AX instead of a byte argument AH.
(get_diskinfo_int13_extensions): Removed.
* stage2/Makefile.am (noinst_HEADERS): Added iso9660.h.
(libgrub_a_SOURCES): Added fsys_iso9660.c.

* stage1/stage1.h (GRUB_INVALID_DRIVE): New macro.
* stage1/stage1.S (boot_drive): Use the macro GRUB_INVALID_DRIVE.
(real_start): Likewise.
* lib/device.c (get_drive_geometry): Set GEOM->SECTOR_SIZE to
SECTOR_SIZE by default.
* configure.ac (--disable-iso9660): New option.
Migrated to newer autotools. Also, don't install mkbimage
because its name is too general and it does not conform to the
GNU Coding Standards in some points.
* util/Makefile.am (EXTRA_DIST): New variable.
(sbin_SCRIPTS): Removed mkbimage.
(noinst_SCRIPTS): Added mkbimage.
* stage1/Makefile.am (AM_ASFLAGS): Renamed to ...

* configure.in: Removed.
* configure.ac: New file. Mostly derived from configure.in.
From Ilguiz Latypov:
* configure.in: Fix a syntax error in a sed script.
* stage2/bios.c (get_diskinfo): PhoenixBIOS 4.0 Revision 6.0
for ZF Micro might understand the greater buffer size for the
"get drive parameters" int 0x13 call in its own way.
Supposedly the BIOS assumes even bigger space is available and
thus corrupts the stack. This is why we specify the exactly
necessary size of 0x42 bytes.
* configure.in (falign_loop_flag): New variable. Set to if GCC
supports `-falign-*'. If true, use `-falign-jumps',
`-falign-loops' and `-falign-functions' instead of
`-malign-jumps', `-malign-loops' and `-malign-functions',
because `-malign-*' are obsolete in GCC 3.x. Reported by Jeremy
Katz.
* docs/grub.texi (General commands): Added ``pager'' into the
menu.
(pager): New subsection.
(terminal): Added a description about the option
``--lines=LINES''.
* configure.in (AC_INIT_AUTOMAKE): Set the version number to
0.92.
