Get a newer version of gnucap.

What doesn't work in 0.35 is that syntax for specifying default 
values.  Passing parameters works.

Get the latest snapshot, where it all works.

The wiki is for the snapshot.  Based on the date, 2009/10/04, 
still not the latest.  In the latest version, the LTspice syntax 
works.
