My mistake, for some reason I misread and thought you had used -Wall. Sorry. However, you still need -Wpedantic -pedantic-warnings, as explained above. GCC is non-conforming unless you ask it explicitly to be a conforming compiler, and even then...
[ -Wall This enables all the warnings about constructions that some users consider questionable, and that are easy to avoid (or modify to prevent the warning), even in conjunction with macros. This also enables some language‐specific warnings described in C++ Dialect Options and Objective‐C and Objective-C++ Dialect Options. ]
