Since ttc_item_offset can never be zero in a ttc, you don't need the
boolean.

Please define and use the 'ttcf' tag.

We already have this define later on, we should probably move it to the top
of the file (under the GET_BE_(D)WORD defines looks like a good place) and
move all the various tag definitions up there too. This should be done as
a separate, preliminary patch.

I find the introduction of tag here confusiong. You should be able to
do this without the second variable.

Doesn't this print the tag backwards?
Huw.
