unnamed fields of type other than struct or union are not allowed

[Luben Tuikov]

I have a similar construct:

struct test {
	unsigned char :1;

	int            i;
	int            ;
	long           l;
};

and the compiler complains:

somefile.c:line#: unnamed fields of type other than struct or union are not allowed

This used to work with gcc 3.0.4 and before.

Can someone tell me why the bitfield is ok to be unnamed but
the int cannot be unnamed?

Thanks,
