configure --enable-no-install-program=groups now works.
+ "cp -fR fifo E" now succeeds with an existing E. Before this fix, using
+ -fR to copy a fifo or "special" file onto an existing file would fail
+ with EEXIST. Now, it once again unlinks the destination before trying
+ to create the destination file. [bug introduced in coreutils-5.90]

dd once again works with unnecessary options like if=/dev/stdin and
of=/dev/stdout. [bug introduced in fileutils-4.0h]
