Thanks for the responses. As for the machinations required at this point for Sundials on Windows? Don't have the skill set. No Cygwin here. Instead, installed according to https://github.com/stevengj/julia-mit/blob/master/README.md and using IJulia. Added Sundials via Pkg.add("Sundials"). Seems to add OK.
So would have to install Cygwin, configure Cygwin, make alterations to Sundials.... In time I would hope one could access a stiff ODE solver as easily as one can access ode23 in the ODE package. So thank you Tony and Jameson, but I'll have to wait for a slightly simpler approach of when the BinDeps build becomes more compatible with Windows. I'd love to help develop, but I fear both my coding skills and my development skills are both not up to the task... I know enough to know that I don't know enough. In the meantime, thank you to Alex, I'll try DASSL and see how if that might work.
