Re: const static initializers versionitis

help - please ...

Why were forward declarations of const arrays removed from g++
since 2.95.2 ?

Isn't this a gcc bug ? i.e. not being able to forward declare an
array instance ?

The code still compiles fine in gcc so I would have some level
of expectation that "const"ness should not change the behaviour
of the compiler.

Is there a compiler switch that reinstates the desired behaviour ?

const static struct foo bar[];

const static struct foo tar[];

const static struct foo bar[] = {
        tar, "bar"
};

const static struct foo tar[] = {
        bar, "tar"
};

const char * zefuc()
{
        return tar->y->who;
}
