I think this might be a weird old leftover, ngspice goes all the way back to SPICE3 essentially.

Aside from pulling out the other stuff we don't need, this looks good. Thanks @barracuda156. Your commitment to keeping new stuff running on old stuff running is pretty legendary.

I have a Pismo with 10.4 that I only use to write papers. I probably should check against that as a habit. @barracuda156 thanks for being on top of it and @markemer, thanks for fixing it up.
