These must not be set unconditionally because not all systems understand
e.g. @samp{LANG=C} (notably SCO). Fixing @code{LC_MESSAGES} prevents
Solaris @command{sh} from translating var values in @code{set}! Non-C
@code{LC_CTYPE} values break the ctype check. Therefore, run:
@code{LC_CTYPE} values break the ctype check. @code{LANGUAGE} is a
@sc{gnu} extension.
@example
test "$@{LANG+set@}" = set && LANG=C && export LANG
test "$@{LC_ALL+set@}" = set && LC_ALL=C && export LC_ALL
test "$@{LC_CTYPE+set@}" = set && LC_CTYPE=C && export LC_CTYPE
test "$@{LC_MESSAGES+set@}" = set && LC_MESSAGES=C && export LC_MESSAGES
@end example
@emph{If} one of these variables is set, you should try to unset it,
using @samp{C} as a fall back value. see @ref{Limitations of Builtins},
builtin @command{unset}, for more details.
