Ahh...and -I/usr/include causes gcc (inside gccxml) to remove it from
later in the include path and therefore not found by include_next.

However, I think it is still a gccxml problem because

  g++-4.3 -I/usr/include test.cc

works.  I'll need to investigate it further.  Please submit a bug report:
