ANOVA, GLM and missing values

In the software implementations of ANOVA that I have seen, missing
values are not allowed. To analyse ANOVA-type data with missing values
I have to use GLM, which ANOVA reduces to under certain circumstances.


Having now read a little about GLM, I am unable to see why it should
allow missing values when ANOVA apparently does not. As far as I can
see, the generalization from ANOVA lies in the conceot of a link
function, and allowing this to be something other than the identity
function ushers in a new dimension of modelling possibilities.
However, when the link function is the identity function, GLM is
supposed to reduce back to ANOVA ...

So I fail to see what else GLM brings to the party which allows
missing values to be tolerated. I'd be grateful for any insights.
