Yes, but the web site is severly out-of-date. I'm still waiting for a stable version of Open Watcom which incorporates the required RDOS fixes. Currently, I need to use the OW fork and build it from source. Most of the code can be found in the SVN-link, but it requires building Jiri Malaks fork of OW in order to work.
Edit: Alternatively, people can use this pre-built OW package which would install a working compiler for RDOS:
