There no chance of fixing this for 3.1.0; BUT we should ask for clarification so we can get it fixed in 3.1.1 if it is agreed to be a bug. Everyone should read this as: REPORT ALL GCC BUGS YOU FIND :-) to "gcc-bugs@gcc.gnu.org". It is our responsibility to assist in making GCC 3.1.x the best GCC yet as the C compiler is one of our fundamental tools and its quality directly affects us.
