Switcap backend doesn't work completely, like it does in gEDA/gaf about lepton-eda

[graahnul-grom]

@AweVision7 Steven, thank you for the report.
Could you please attach a simple schematic to test
the backend along with expected and actual output?

I get a backtrace while running the following command
in utils/netlist/examples/switcap:
lepton-netlist -g switcap -o - ckt.sch clocks.sch analysis.sch

Backtrace:

@AweVision7 Please try this patch, it works for me.
Apply it to the latest git sources with
git apply gnet-switcap.diff.txt

@AweVision7, as @graahnul-grom already asked, could you please provide us with a simple test schematic to include it in the test suite?

[vzh]

Ah, I see, the example is also in the examples/ directory. Sorry for the noise.

@AweVision7, have you ever used the SWITCAP program itself, I mean sw or sw2? I've not found a way to download it anywhere.

JFTR, just found: http://innovation.columbia.edu/technologies/Proxy30_optimal-simulator-for-mixed/licensing

Hmm, they require my phone number for signing up. Why? Leaving out.
