This patch fixes the compile warning in tgt-vvp/scope.c when using gcc-4.6.1. It basically removes the unneeded code, points to the correct code in V0.8 so that this is implemented correctly if/when synthesis is added back to Icarus and asserts that the sync/async set/clear are not used. These asserts will trip when the code needs to be reworked.
There are patches for both development and V0.9. There are no test suite changes.
