# William Roadcap was the original author of Menuconfig.
# Michael Elizabeth Chastain (mec@shout.net) is the current maintainer.
#
# 070497 Bernhard Kaindl (bkaindl@netway.at) - get default values for
# new bool, tristate and dep_tristate parameters from the defconfig file.
# new configuration parameters are marked with '(NEW)' as in make config.
#
# 180697 Bernhard Kaindl (bkaindl@netway.at) - added the needed support
# for string options. They are handled like the int and hex options.
#
# 081297 Pavel Machek (pavel@atrey.karlin.mff.cuni.cz) - better error
# handling
#
# 131197 Michael Chastain (mec@shout.net) - output all lines for a
# choice list, not just the selected one. This makes the output
# the same as Configure output, which is important for smart config
# dependencies.
#
# 101297 Michael Chastain (mec@shout.net) - remove sound driver cruft.
#
# 221297 Michael Chastain (mec@shout.net) - make define_bool actually
# define its arguments so that later tests on them work right.
#
# 160198 Michael Chastain (mec@shout.net) - fix bug with 'c' command
# (complement existing value) when used on virgin uninitialized variables.
#
# 090398 Axel Boldt (boldt@math.ucsb.edu) - allow for empty lines in help
# texts.
#
# 12 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
# Remove a /tmp security hole in get_def (also makes it faster).
# Give uninitialized variables canonical values rather than null value.
# Change a lot of places to call set_x_info uniformly.
# Take out message about preparing version (old sound driver cruft).
#
# 13 Dec 1998, Riley H Williams <Riley@Williams.Name>
# When an error occurs, actually display the error message as well as
# our comments thereon.
#
# 31 Dec 1998, Michael Elizabeth Chastain (mec@shout.net)
# Fix mod_bool to honor $CONFIG_MODULES.
# Fix dep_tristate to call define_bool when dependency is "n".
#
# 02 January 1999, Michael Elizabeth Chastain (mec@shout.net)
# Blow away lxdialog.scrltmp on entry to activate_menu. This protects
# against people who use commands like ' ' to select menus.
#
# 24 January 1999, Michael Elizabeth Chastain, <mec@shout.net>
# - Improve the exit message (Jeff Ronne).
#
# 06 July 1999, Andrzej M. Krzysztofowicz, <ankry@mif.pg.gda.pl>
# - Support for multiple conditions in dep_tristate().
# - Implemented new functions: define_tristate(), define_int(), define_hex(),
# define_string(), dep_bool().

There seems to be a problem with the lxdialog companion utility which is
built prior to running Menuconfig. Usually this is an indicator that you
have upgraded/downgraded your ncurses libraries and did not remove the
old ncurses header file(s) in /usr/include or /usr/include/ncurses.
It is VERY important that you have only one set of ncurses header files
and that those files are properly version matched to the ncurses libraries
installed on your machine.
You may also need to rebuild lxdialog. This can be done by moving to
the /usr/src/linux/scripts/lxdialog directory and issuing the
"make clean all" command.
If you have verified that your ncurses install is correct, you may email
the maintainer <asmax@videolan.org>.
