CMD script shows label behavior difference

Wine's cmd.exe behaves differently regarding redefined labels in cmd/bat files.
With Wine, it appears that the interpreter jumps to the last label with the
correct name seen before a "goto" command, on Windows, it will jump to the next
label after a "goto" command.

Please see the attached test file, it should make things clear. It will produce
the output "I'm wine!" or "I'm windows!" respectively.

While it is certainly bad practice to redefine labels, unfortunately CMake
creates such batch files when creating custom commands for Visual Studio
builds.
