It's necessary to set the standard manually to c89 or gnu89 now that GCC defaults to -std=gnu11. Now that GCC has carets for its diagnostics, we can see that the 2 warnings actually point to different places: $ /usr/local/bin/gcc -c -std=gnu89 -pedantic 37200.c 37200.c: In function ‘foo’: 37200.c:10:11: warning: initializer element is not computable at load time [-Wpedantic] { (void**) &x->tst } ^ 37200.c:10:3: warning: initializer element is not computable at load time [-Wpedantic] { (void**) &x->tst } ^ So are they still actually duplicates?
