It's new in R-devel (part of the attempt to make cross-building more maintainable). It's a mistake in the archive and it will be commented out come the final release barring snafus.

The shell is not often `MS-DOS' (command.com): e.g. I use tcsh, DJM uses bash and Windows Xp uses cmd.exe. The first two do not look in the current directory by default, and so do need `.' in the path to find e.g. Rpwd.exe.
