If I were going to look into the behavior on Windows, I'd probably
want to use Windows native features. (I tried my test on Cygwin,
and the callee wasn't invoked.)
Apparently the Windows way to invoke a program is CreateProcessA().
But it takes the command line as a single string. There might not
be a Windows-native way to exercise the kind of control over argc
and argv provided by POSIX execve().
