What must be avoided is -pedantic diagnostics forstruct flex1 { int n; int data[1]; }; struct out_flex_end1 { int m; struct flex1 flex_data; }; regardless of whether considered flexible or not, since that's clearly valid in standard C.
Are you sure about "regardless of whether considered flexible or not", since ISTM the validity of the above in standard C is limited to when it's considered a non-flexible array. So with -pedantic it shouldn't warn, but it also then shouldn't consider it a flexible array.
In other words, perhaps it makes sense to imply -fstrict-flex-arrays with -pedantic?
