* disk/ata.c (enum grub_ata_commands): Remove EXEC_DEV_DIAGNOSTICS.
(enum grub_ata_timeout_milliseconds): New enum.
(grub_ata_wait_status): Add parameter milliseconds.
(grub_ata_cmd): Remove variable `err'. Remove wait for !DRQ to allow
recovery from timed-out commands.
(grub_ata_pio_read): Add parameter milliseconds. Fix error return,
return grub_errno instead of REG_ERROR.
(grub_ata_pio_write): Add parameter milliseconds.
(grub_atapi_identify): Fix size of ATAPI IDENTIFY sector.
Pass milliseconds to grub_ata_wait_status () and
grub_ata_pio_read ().
(grub_atapi_packet): Pass milliseconds to grub_ata_pio_write ().
(grub_ata_identify): Remove variable `ataerr'. Pass milliseconds to
grub_ata_wait_status (). Fix IDENTIFY timeout check.
(grub_ata_device_initialize): Remove EXECUTE DEVICE DIAGNOSTICS.
It is not suitable for device detection, because DEV bit is ignored,
the command may run too long, and not all devices set the signature
properly.
(grub_ata_pciinit): Clear grub_errno before grub_ata_device_initialize ().
(grub_ata_setaddress): Pass milliseconds to grub_ata_wait_status ().
Fix device selection, DEV bit must be set first to address the registers
of the correct device.
(grub_ata_readwrite): Pass milliseconds to grub_ata_wait_status () and
grub_ata_pio_read/write ().
(grub_atapi_read): Pass milliseconds to grub_ata_pio_read ().
(grub_atapi_write): Pass milliseconds to grub_ata_pio_write ().
* Makefile.in: Add `target_os' and `enable_grub_pe2elf'.
* conf/common.rmk: Install `grub-pe2elf' only if requested.
Install `grub.d/10_windows' only on Cygwin.
* configure.ac: Add subst of `target_os'.
Check `target_os' also before setting TARGET_OBJ2ELF.
Add `--enable-grub-pe2elf'.
* kern/i386/pit.c (TIMER2_SPEAKER): New define.
(TIMER2_GATE): Likewise.
(grub_pit_wait): Add enable/disable of the timer2 gate
bit of port 0x61. This fixes a possible infinite loop.
* util/update-grub.in: Add a check for admin
group on Cygwin.
Remove old `grub.cfg.new' before creation.
Add `-f' to `mv' to handle the different filesystem
semantics of Windows.
* util/i386/pc/grub-install.in: If `--debug' is specified,
pass `--verbose' to grub-setup.
Abort script if make_system_path_relative_to_its_root() fails.
* commands/cat.c (grub_cmd_cat): Remove non-ESC keys from keyboard queue
to ensure that break with ESC will always work.
* commands/sleep.c (grub_interruptible_millisleep): Likewise.
Remove ESC from keyboard queue.
* util/biosdisk.c: [__CYGWIN__] Add includes.
(grub_util_biosdisk_open): Use Linux code also for Cygwin.
(get_os_disk): Move variable declarations to OS specific
parts to avoid warning.
[__GNU__] (get_os_disk): Fix /dev/sdXsN case.
[__CYGWIN__] (get_os_disk): Add Cygwin /dev/sdXN device names.
(grub_util_biosdisk_get_grub_dev): Use Linux code also for
Cygwin.
* util/getroot.c: [__CYGWIN__] Add includes.
(strip_extra_slashes): Fix "/" case.
[__CYGWIN__] (get_win32_path): New function.
[__CYGWIN__] (grub_get_prefix): Add conversion to win32 path.
[__CYGWIN__] (find_root_device): Disable.
[__CYGWIN__] (get_bootsec_serial): New function.
[__CYGWIN__] (find_cygwin_root_device): Likewise.
[__linux__] (grub_guess_root_device): Add early returns to simplify
structure.
[__CYGWIN__] (grub_guess_root_device): Call find_cygwin_root_device.
[__linux__] (grub_util_get_dev_abstraction): Enable LVM and RAID
check for Linux only.
