I've started writing a patch, and there are sooo many "error" calls
all over this sim...  It'll be a larger patch than I thought.

For 7.12.1, the simplest would probably be to give GDB's "error"
function extern "C" linkage.

Meanwhile, if you're not interested in the sim,
you should be able to workaround this by configuring
with --disable-sim.

Chris, could you open a bug report in bugzilla?
