No, it works in real ksh.  If the last command in a pipeline is a
builtin, it is run in the current shell.

$ unset foo bar
$ echo ${foo=hiya} | read  bar
$ echo foo=$foo bar=$bar

the above will set bar but not foo in ksh.  Some shells will set foo
but not bar.  Current bash sets neither.  No shell sets both.

But not Cygwin-related.
