Hmm, the checks for Cygwin should only be in spkg-install files, and
those are mostly to apply Cygwin-only patches.
As far as cephes is concerned, if you need it, you should be able to
change
#!/usr/bin/env bash
if [ "$UNAME" != "CYGWIN" ]; then
echo "We do not install the cephes library on any operating system
except Cygwin."
exit 0
fi
appropriately. But checks for Cygwin shouldn't impact other systems,
including FreeBSD.
