The backend drc2 should also be able to check spice netlists. The only
problem is that the pintype attribute should be defined in the symbols. 
As an example, I can get the given schematic free of errors if add the
pintype attribute to the resistor-1.sym symbol. The attached diff is:

I think that the user should always have a verification tool (the drc2
backend in this case) to search for possible errors and validate the
schematic, no matter what kind of netlist he will be using. In order to
do this painfree, some symbol work is needed (adding the pintype
attribute). I think it's worth to do it.

gsymcheck reports a warning if the pintype attribute is not set in the
symbol... why not look at the warnings and set that attribute when doing
the symbol?
