New description:
At some point a dependency on the mc library was added, but this is not
available by default on Cygwin (this surely lives in a very common and
useful package, but I've reinstalled Cygwin recently and it has not
appeared yet) and is not needed anyway.
So the dependency should be removed thus avoiding overlinking and build
failure where this lib is not available.

Oh, that's where they lived! Yes, they are there.
> But what you just pointed out and confirmed is that linking to these
files (and so installing Cephes) is not needed anymore on Cygwin.
Agreed.
