commit 70fc13d3bab5c29591dd0d8d020dbef27a7e2caf

    Fix native machine reported on x86_64 without IsWow64Process2()
    
    If the OS version is old enough not to have IsWow64Process2(), and
    IsWow64Process() returns FALSE, this only indicates x86 for an x86
    process.
    
    Fixes 4936dbc.
