Hello maintainers,

There are three issues on sim/rx.
1. A committer have forgot run autoheader.
2. There doesn't use config.h in main.c.
3. We should check if the host has getopt.h

The attached patch is enough to build on OSX host.
It's possible there are another issues around portability there.

Thanks,
