g++ unqualified-id error gives wrong line

[Boyd Montgomery]

Compile the following code, which is missing a semi-colon on the last line:

class WrongLine {
WrongLine() {
}
private:
int n;
}

In g++ 4.0.3 (Ubuntu 4.0.3-1ubuntu5), the above yields:
GBug.h:3: error: expected unqualified-id at end of input

But its actually line 6 where the error occurs, which can be fixed by
changing line 6 to };
