typedef struct PurpleAccount PurpleAccount;
That means that if you include account.h you can't do
account->username, because "account" is an incomplete type, just like
a void *. Note also that PurplePresence doesn't need to be defined in
account.h, hence you remove a header dependency for all the files that
include account.h, and you remove all the headers that presence.h
include, and so on.
After cleaning up that mess in msn-pecan compilation time was reduced
quite dramatically. You should try to the some in a few places ;)
Oh, now I remember a criticism to this approach. Somebody mentioned
that this breaks the API. But again, that's not true. The account.h
that gets installed doesn't need to be the one used internally.
For example, account.h could be split into account_public.h and
account_private.h. Stuff in libpurple would use one of these two
headers, preferably the public one. Then, account.h includes them

I can already do that, but why not remove the middle man's if
libpurple is so painful to use?

Great! I propose an API version field, then.
