Ext2 Filesystems Utilities

the script lib/ss/ct_c.sed uses things like 'a-z', but
the calling env does not make sure that the locale has
been set to C first

quick fix is to add:
export LC_ALL=C
to the top of lib/ss/mk_cmds.sh.in

but you may prefer to add the more lengthy/standard GNU
approach:
# NLS nuisances.
for as_var in \
LANG LANGUAGE LC_ADDRESS LC_ALL LC_COLLATE LC_CTYPE
LC_IDENTIFICATION \
LC_MEASUREMENT LC_MESSAGES LC_MONETARY LC_NAME
LC_NUMERIC LC_PAPER \
LC_TELEPHONE LC_TIME
do
if (set +x; test -z "`(eval $as_var=C; export
$as_var) 2>&1`"); then
eval $as_var=C; export $as_var
else
unset $as_var
fi
done
