 I would like to update this bug report.
 
 I heard that some gcc3.1 in the past doesn't have this bug and so I've
 tried to find the first version in which it appeared.
 
 The result is that version gcc version 3.1 20011212 (experimental) is
 correct ie without this bug and next version gcc version 3.1 20011213
 (experimental) has this bug.
