Doing an overnight build of all rtems targets, I can across this new breakage for m68k-rtems4.7. I last built this target on Nov 3 from the head and it compiled then.

This is with gcc SVN head as of yesterday afternoon, binutils 2.16.1 and newlib 1.13.0.I can file a PR but this is definitely a recent breakage.
