    Dedupe include dirs inherited from dependencies · 6e31b30d
    Bartosz Nitka authored
    If you build a big number of packages, all with
    the same extra -I flags, the flags get inherited
    by the dependent packages and duplicated.
    For big dependency trees it can exceed the
    maximum command line length on some systems,
    this happened to me with Linux and hoogle 5.
    This patch decreases the redundancy by
    dropping all but the first occurrence of
    an include dir, preserving the semantics,
    as they are processed left to right.
