[Bug c++/31941] New: [4.1/4.2/4.3 Regression] "confused by earlier errors" message without earlier error message

[tbm at cyrius dot com]

With the attached source, 4.0 prints and error and then says that it got
confused by earlier errors.  In 4.1 and 4.2, however, it gets confused
without actually printing the earlier error:
