Now finished, and here is another way to check if your library is OK or
not:

wget http://git.savannah.gnu.org/cgit/gnutls.git/plain/tests/hostname-check.c
wget http://git.savannah.gnu.org/cgit/gnutls.git/plain/tests/utils.c
wget http://git.savannah.gnu.org/cgit/gnutls.git/plain/tests/utils.h
gcc -o hostname-check hostname-check.c utils.c -I. -lgnutls
./hostname-check

It should finish with 0 errors.

Maybe we'll need a 2.8.4 to fix this...
