Most of the changes are protected by !POSIXPERM but one of them
seems to use MINGW, which looks inconsistent and I suspect was not a
distinction made on purpose.  The above description sounds to me
that the !POSIXPERM prerequisite is the right thing to use.

I am not sure if it is a good idea to sprinkle test-have-prereq and
make the test script test different things on different platforms,
though.
