* configure.in (--enable-serial): Changed to ...
(--disable-serial): ... this. Now the serial support is enabled
by default.

* stage2/char_io.c [!STAGE1_5] (get_cmdline) [!SUPPORT_SERIAL]:
Don't check if the terminal is dumb. If the terminal is console,
always use console functions.
* stage2/builtins.c [!SUPPORT_NETBOOT] (bootp_func): Undefined.
[!SUPPORT_NETBOOT] (builtin_bootp): Likewise.
[!GRUB_UTIL] (device_func): Likewise.

(builtin_table) [!SUPPORT_NETBOOT]: Removed the pointers to
BUILTIN_BOOTP, BUILTIN_DHCP, BUILTIN_RARP, and
BUILTIN_TFTPSERVER.
(builtin_table) [!SUPPORT_SERIAL]: Removed the pointers to
BUILTIN_SERIAL and BUILTIN_TERMINAL.

Texinfo release. See the webpage

* GNU Automake 20000319 or later
* Our version of GNU Automake
The new feature "per-executable flags" is required, so you need to
get an unreleased version from the CVS. See the webpage
<http://sourceware.cygnus.com/automake/>.
We use the new feature "per-executable flags" in the CVS version, but
it is too buggy for us, so a locally patched version is required at
the moment. You can obtain this from
<ftp://duff.kuicr.kyoto-u.ac.jp/pub/grub/automake-1.4a-for-grub.tar.gz>.
NOTE: This is a temporary solution. We will use the official version
again, once they fix the critical bugs.

`--without-curses'
Don't use the curses library.
`--disable-serial'
Omit the serial terminal support in Stage 2.
`--enable-serial-speed-simulation'
Simulate the slowness of a serial device in the grub shell. This
option is useful for GRUB developers, as you can test the
performance of a terminal emulation even on pseudo terminals.
`configure' also accepts several options for the network support. See
the file `netboot/README.netboot', for more information.
