Eigler * sim-gx-run.c (sim_engine_run): Allay warnings. Write out updated gx block list after each successful compilation job. * sim-gx.c (sim_gx_compiled_block_f): dlopen the main executable image, to allow gx block DLLs to resolve symbols there. (sim_gx_{read,write}_block_list): Allay warnings. (sim_gx_block_translate): Allay warnings.
