I don't think so. AFAIK, RSXNTDJ generates Win32 native apps,
i.e. pretty normal Windows programs. Meaning they're as infectable or
immune as any other Win32 app out there is. No special protection in
sight. The more advanced Win32 viruses may have problems with its
different layout (less slack space in the COFF to hide in, or
something like that), but I'm not sure about that.

The essential thing is really security by obscurity, here, I think.
DJGPP and RSXNTDJ compiled apps are too rare to act as the host for
any 'successful' virus.
