src RPM junk (to clean up before the real release)

[Henry Cejtin]

The following files were in the source RPM but look like garbage:
	mlton-20010616/src/benchmark/Makefile~
	mlton-20010616/src/benchmark/main.sml~
	mlton-20010616/src/benchmark/benchmark.cm~
	mlton-20010616/src/benchmark/junk~
	mlton-20010616/src/mlton/cps/contify.old.fun
	mlton-20010616/src/mlton/xml/simplify.fun.older
	mlton-20010616/src/lib/mlton/basic/regexp.old.sml
	mlton-20010616/src/benchmark/junk
	mlton-20010616/src/mlton/codegen/x86-codegen-old and everything in it
Also, and this is important, many of the files are group writable.  It seems
pretty random, but I would think that the mode you want for most files is
644, not 664.
