footnote.dtx (\fn@endnote): Use `\def', not `\let'.

If the `color' package is loaded /after/ us then it redefines
`\color@begingroup' and `\color@endgroup' to actually do things, but it
won't redefine `\fn@endnote' for obvious reasons.  As a result,
`\fn@startnote' will now open a colour group, but nothing will close it
and one ends up on a debugging odyssey.
