SourceTagTable.sourceTagTableAddTags needs to convert a [SourceTag] to a
GSlist
SourceTag.keywordListTagNew needs to convert a [String] to a GSList

I've questioned it on one of the gtk lists. I've not got any response
yet, if I don't get a reply I'll file it as a bug or ask the author.

Only thing missed was my errata to the Makefile, here's a patch against
the current cvs:

I am having problems binding the SourceMarker module (and the various
marker function in the SourceBuffer module). The problem is that
GtkSourceMarker is a typedef of GtkTextMark (rather than a subclass) and
c2hs doesn't understand that so all the {#call #}'s get turned into
foreign import declarations using Ptr () rather than Ptr SourceMarker or
Ptr TextMark.

I'm not sure how to get around this, it's not just a matter of sticking
castPtr everywhere as there's all the withforiengPtr business too. I
could try pretending that GtkSourceMarker is a subclass of GtkTextMark.
That should work as I don't think any code relies on being able to
convert a GtkTextMark to a GtkSourceMarker (which is allowed if they are
aliases but not if the have a super/subclass relationship). I've
attached my current attempt so you can see what I'm talking about.
