r256683 committed to GCC 8 to avoiding duplicate instances of -Wstringop-overflow warnings on some targets has the unintended side-effect of suppressing even singleton instances of the warning in cases such as 'strcat (strcpy (buf, "hello "), "world!")' when _FORTIFY_SOURCE is defined. The attached patch restores the warning for the trunk. Since this is a regression in a security feature and the warning isn't prone to false positives (I don't think I've seen any when _FORTIFY_SOURCE is defined), I'd also like the fix considered for the 8 branch. Thanks Martin
