I dunno, but I agree this is suboptimal and should be improved. I
suspect the reason has to do with the push/pull layers, which I'm
unfamiliar with. Patches welcome.

This I can answer -- in 1.1 all types have been renamed, to *_t. So
you are likely reading 1.1 documentation, but using 1.0. All 1.0
types should still work in 1.1, though. But the examples are correct
in using *_t. See the links from
<http://www.gnu.org/software/gnutls/documentation.html> for which
manual correspond to the stable and development branch.
