mknod: new module
Solaris 9 mknod("name/",mode,dev) mistakenly creates "name" for
non-directory mode. FreeBSD 7.2 mknod("dangling/",mode,dev)
mistakenly creates the target of the symlink if run as root.
FreeBSD and OpenBSD mknod("fifo",S_IFIFO|mode,0) fails for non-root.
Use of mknod caused link failures on mingw.
