Sync to commit 7333d9c:  Fix build failure when compiling IntAna_Curve.cxx

    This bug had been introduced when upgrading OCCT-patches
    to OCCT 6.7.0.  We patched src/IntAna/IntAna_Curve.cxx
    in c35fc63 to get rid of compiler warnings.
    A different fix has been applied in OCCT 6.7.0, the
    final return has been dropped, so our change has to
    be removed from
