commit 341df2bdc3f9664587a57f947249c3208da77c9b

    dtc: Add -Wredundant-decls (resend)
    
    We are almost clean already with the -Wredundant-decls warning.  The
    only exception is a declaration for isatty() inside the flex-generated
    code.  This can be removed by using flex's "never-interactive" option,
    which we probably should be using anyway, since we never parse
    interactively in the sense that this option implies.
