While trying to compile coreutils with -Wextra, I noticed many warnings due to automatic variables initialized with { 0, }.
As I understand it, since C90 the above will initialize [all members of] the type to that used in static scope. I.E. the following is valid: mbstate_t m = { 0, }; int i = { 0, }; struct { int a; int b; } s = { 0, }; It would be great I think if gcc would relax this warning in the specific case where { 0, } is specified. I.E. with a trailing ',' as that would be clear indication that one wants to init all elements to 0, and that we haven't just forgotten some members. thanks, Pádraig.
