[dmd-internals] auto-tester failures

[Brad Roberts]

Well, looks like the auto-tester has been failing for some time now, since the
5th at around midnight.

Last good run:
  http://d.puremagic.com/test-results/test.ghtml?runid=1260
  dmd r702

Test run 1261 caused the dmd tests to start failing on both win32 and linux32:
  http://d.puremagic.com/test-results/test.ghtml?runid=1261
  dmd r703

Test run 1262 caused dmd on linux32 to fail to build successfully.
  http://d.puremagic.com/test-results/test.ghtml?runid=1262
  dmd r703

phobos and druntime versions didn't change between good and failures.
