4.4 doesn't print the function names in the error message, while 4.5 and 4.6 do
so:

$ cat  foo.c
void foo(const char *p, int cond, int a, int b)
{
        p[cond ? a : b] = '\0';
}

$ gcc-4.4 -c foo.c
foo.c: In function 'foo':
foo.c:3: error: assignment of read-only location '*(p + (cond != 0 ? (long
unsigned int)(long unsigned int)a : (long unsigned int)(long unsigned int)b))'

$ gcc-4.5 -c foo.c
#'c_maybe_const_expr' not supported by pp_c_expression#) != 0 ? (long unsigned
int)a : (long unsigned int)b) * 1ul))'foo.c: In function 'foo':
foo.c:3:2: error: assignment of read-only location

is the new format expected?
