[This was originally reported on the cygwin list, but is an
upstream issue in coreutils, tcsh, or both]

The problem is that tcsh 6.14.00 treats LS_COLORS as a magic
environment variable, also parsing it for its own use in the
tcsh builtin ls-F.  This means that coreutils dircolors, when given
an SUID coloration, will output data that is expected by coreutils
ls but unexpected by unpatched tcsh.
