class Foo
{
    static int test()
    {
        return c_func();
    }

    extern(C) __gshared int c_func();
}

test.d(7): Error: need 'this' to access member c_func

The docs say:
__gshared may also be applied to member variables and local variables. In these
cases, **__gshared is equivalent to static**, except that the variable is
shared by all threads rather than being thread local.

And true enough it works fine with regular variables:
class Foo
{
    static int getX() { return x; }
    extern(C) __gshared int x;
}

But not with function pointers, unless they're declared outside the class. I think this is a bug.

Ok. But why is 'static' required? This won't work:

class Foo
{
    static int test()
    {
        return c_func();
    }

    extern(C) int c_func();
}

test.d(5): Error: need 'this' to access member c_func
