Any C++ compiler should reject that; it's not legal C++.  Even for int
constants, the only way to initialize them is via the constructor's
initialization list:

        class foo {
           const int i;
           foo();
           //...
           };

        foo::foo(): i(10) { }

Of course, that means you can't use constant members for things like array
bounds and the like, where a constant expression is required.  For that, you
can use an enumeration constant:

        class bar {
           enum { ARRAY_SIZE = 100 };
           int array[ARRAY_SIZE];
           //...
           };
