[boost] [date time] gcc 4.3 compile error

I want to report the following unexpected error that I got compiling the  
"dates as strings" example with gcc 4.3.0 (svn 2008 01 28 )

The error is produced with and without the -Wall option. Compiling with  
gcc 4.2 all goes fine.
Is it a gcc 4.3 bug or the compiler is pointing out an actual non-strict  
iso-compliant coding issue ?

I attached a text file with verbose compile output.
