IntersectionOperator fails to build with GCC 4.7

[Johannes Ring]

After upgrading to GCC 4.7 I get errors like this when building the 1.0.x branch:

  /home/johannr/dev/fenics/src/dolfin/1.0.x/dolfin/intersection/IntersectionOperator.cpp:242:1: required from here
  /home/johannr/dev/fenics/src/dolfin/1.0.x/dolfin/intersection/Segment_3_Tetrahedron_3_intersection.h:61:12: error: ‘dolfin_error’ was not declared in this scope, and no declarations were found by argument-dependent lookup at the point of instantiation [-fpermissive]

The complete error message can be found here:

  http://paste.ubuntu.com/986782/

Applying the patch from revision 6663 in trunk fixes the problem:

  http://bazaar.launchpad.net/~dolfin-core/dolfin/trunk/revision/6663

Is that an acceptable fix?
