#3588 Cygwin regression testing doesn't work

[Philipp Klaus Krause]

When trying to do regression testing on Cygwin,

something is wrong: the initial setup that I see happen once on GNU/Linux apparently happens twice (and twice again on any subsequent next make, while on GNU/LInux it happens zero times on subsequent make), and after that the testing does not proceed:
