    Switch "cl /?" to "cl /help" in MSVC scripts for platform detection · 733d6700
    Michael Paquier authored
    "cl /?" produces a different output if run on a real or a virtual drive
    (this can be set with a simple subst command), causing an error in the
    MSVC scripts if building on a virtual drive because the platform to use
    cannot be detected.
    
    "cl /help", on the contrary, produces a consistent output if used on a
    real or virtual drive.  Changing to "/help" allows the compilation to
    work with a virtual drive as long as the top of the code repository is
    part of the drive, without impacting the build on real drives.
