It's the way env works, especially in conjunction with '#!'. If you
really want to do this, create a wrapper script, where you can define
all the flags. In this example, the interpreter Cygwin or Linux or any
other OS will call up is "bash -vx", which is it not a valid interpreter
name ("bash" by itself is of course).
