Munging of paths passed inside the system() interpreter command is no longer supported. You have to pass your paths to posix_spawn() or the execve() family of functions if you want them to be munged. The first three characters must match `^/[a-z]/` in which case, it'll be turned into a DOS-style drive path with backslashes.
