 The most recent testresults showing it failing seem to be
 http://gcc.gnu.org/ml/gcc-testresults/2002-04/msg00009.html
 - I don't know if this means it is now fixed, someone should have noticed 
 that their patch fixed it if so (if doing proper before-and-after 
 comparisons to detect regressions), unless it only failed on certain 
 platforms.

    Looks as fixed as its going to be.  If there is a still a 
    problem (which nobody seems to be sure about one way or
    the other), we can open a new PR.

 The testcase is 20011223-1.c from the date it was committed, not
 20010606-1.c.

Responsible-Changed-Why:
    No longer looking at this PR.  The audit trail contains a
    patch for the relevant C front end problem, and this is
    still a regression of sorts relative to 2.95, but no-one
    looked at the optimizer issues.
