[Help-gnutls] gnutls 1.2.3 type conflicts

[Daniel]

As reported in:
http://bugs.gentoo.org/show_bug.cgi?id=90976

gnutls-1.2.3 fails under the following condition:
 ./configure --disable-openpgp-authentication  --without-included-minilzo --without-included-libtasn1 --without-included-opencdk --with-zlib

By trying other options the  --disable-openpgp-authentication seems to be the cause.

The output after the above configure line is:

Differing definitions are:

includes/gnutls/gnutls.h:  typedef struct gnutls_openpgp_key_int *gnutls_openpgp_key_t;
libextra/openpgp/openpgp.h:typedef void *gnutls_openpgp_key_t;

and

--
./lib/gnutls_int.h:typedef int (*gnutls_openpgp_recv_key_func) (struct gnutls_session_int *,
./lib/gnutls_int.h-                                          const unsigned char *keyfpr,
./lib/gnutls_int.h-                                          unsigned int keyfpr_length,
./lib/gnutls_int.h-                                          gnutls_datum_t *);
--
./includes/gnutls/extra.h:typedef int (*gnutls_openpgp_recv_key_func) (gnutls_session_t session,
./includes/gnutls/extra.h-                                           const unsigned char *keyfpr,
./includes/gnutls/extra.h-                                           unsigned int keyfpr_length,
./includes/gnutls/extra.h-                                           gnutls_datum_t *key);

Other typedefs may differ and I haven't traced the purpose of these differences.
