* debian/patches/gccxml-workaround.patch: New.  Work around gccxml issue
  with #include_next; c.f. http://www.gccxml.org/Bug/view.php?id=7134.  
* debian/patches/gcc43.patch: include <cstring> in itkNeighbourhood.h.
  This only showed up in the tcl wrapping step.

* Above two entries fix FTBFS for GCC 4.3-based systems.
  Closes: #478500.

* debian/patches/sharedforward.patch: New.  Ensure that linux/sparc
  systems are not also configured as a SUN sparc system, which requires
  SUN header sys/isa_defs.h.  Closes: #478940, #483312.
