[Bug c++/24667] New: -Wcast-qual fails to reject offending cast

["fang at csl dot cornell dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

g++ -Wcast-qual doesn't seem to reject the following code, it just accepts
quitely without warning.  

//======= "foo.cc" ==================
int main(int, char**) {
const int foo[2] = {1,1};
((int*)foo)[0] = 0;
}
//=========================

command: g++ -Wcast-qual foo.cc

program output: (none)

expected output (from g++ 3.3):
foo.cc: In function `int main(int, char**)':
foo.cc:3: warning: cast from `const int*' to `int*' discards qualifiers from 
   pointer target type

keywords: accepts-invalid

known to work: 3.3.x
known to fail: 4.0.2

remarks: possibly closely related to PR 20475
