There need to be (at least) two separate executables: on Windows they are R.exe which invokes Rterm.exe. The reason for this is that "R CMD foo" invokes the script foo, it doesn't run Rterm at all. On Unix-alikes the first is a script rather than an exe. The reason the first is a script on Unix is that whoever wrote it preferred the sh script language to C for handling the things it needs to do, but that's not generally available in Windows, so we were stuck with C.
