Its docstring says:

    gnutls-available-p is a built-in function in `C source code'.

    (gnutls-available-p)

    Return list of capabilities if GnuTLS is available in this instance of 
Emacs.

I see that the info documentation says it returns t, so that needs
fixing.

Your point about HAVE_GNUTLS3 is valid, that's true as of commit
583995c62dd424775dda33d5134ce04bee2ae685. Ted, was that intentional?
