Use sed if you want to change backslashes to slashes.

Cygwin provides *UNIX* functionality, remember?

case "$CLASSPATH" in
    *;*) CLASSPATH=`cygpath --path --unix "$CLASSPATH"` ;; 
    */*) ;; # do nothing
    *) CLASSPATH=`cygpath --path --unix "$CLASSPATH"` ;;
esac

I'm not saying that the above is foolproof.  I haven't even tested it.
However, as usual, if everyone would put as much effort into thinking
about solutions as they did with complaining about the terrible terrible
problem, they'd be farther along the path of a solution.

For the record, the old code was broken and buggy.  It "worked" in an
undocumented fashion.  And, perhaps more importantly, the change was
introduced in November.  It is now February.  Get used to it and
move on.
