Yes, uwe is correct. This is not a gcc bug; it is a new warning. The new
gcc ioconf.c is the same as the old gcc ioconf.c in that respect. Both
have the iattr data for dbcool, but the gcc correctly warns because it
is unused. It get's created because of the extra attribute that you've
commented out.
