I was under the impression ( after reading some postings here and from
experimenting with cfront 1.2 ) that a static const data member CAN
have an initial value.

As proof by existence ;-), try this out on cfront 1.2.1:

----------------------------------------
class foo {
public:
   static const int i = 100;
   int a [ i ];

   foo ( ) { ; }
};

main ( ) {
   foo f;
   printf ( "elements in f.a = %d\n", sizeof f.a / sizeof *f.a);
   // should print out 100
}
----------------------------------------

I hope that this working example is not just a fluke, but is rather
either a part ( or soon to be a part ) of the official definition
of the language.

Any comments?
