I'm guessing these checks were disabled because all of the "runtime/printf" checks together were too verbose when the original check-webkit-style was committed in 2009 in r45857. However, this meant that functions like strcat() and strcpy() were allowed to be committed into the WebKit tree at various times (see Bug 170994). We should turn these checks back on under a new category.
