I will as a Fortran contributor/maintainer oppose inclusion of additional warnings under -Wall unless there is some miraculous compelling reason to include them. With my own Fortran projects, I already need to add "-Wno-maybe-uninitialized -Wno-conversion -Wno-integer-division" after -Wall, because options are just too damn noisy. In fact, I would be in favor of removing -Wall, as it is misnamed, in favor of -Wlevel=0,1,2,3... -Wlevel=0 default warnings. -Wlevel=1 is equivalent to -Wall. -Wlevel=2 is -Wall -Wextra (and maybe -Wsurprising). -- Steve
