["radoslaw dot biernacki at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

typeof() does not property recognizes the non-const type, which was casted from
const type:

$ cat plik.c
#include <stdio.h>

int main()
{
    const unsigned long val;
    typeof( ((unsigned long)(val)) ) val2;
    val2 = 0; //compilation error
}

$ gcc -o plik plik.c
plik.c: In function âmainâ:
plik.c:7: error: assignment of read-only variable âval2â

$ gcc --version
