     48          <para>[renodr] - Add a patch to permit building qtwebengine on i686.
     49          This is due to the alignof operator being changed in GCC 8, as it
     50          returns an incorrect value on 32-bit machines.</para>

     177      If you are building on a 32-bit i686 system, GCC changed the alignof
     178      operator to optimize the ABI. Unfortunately, this makes the alignof()
     179      operator return an incorrect number (4 instead of 8). Apply a patch to
     180      fix this:
