This patch improves the GnuTLS back-end to make the SSL connection phase
non-blocking when the multi interface is used.
GREAT! Many thanks for this improvement. When trying it out, I noticed that
our tests all failed when we built with GnuTLS which made suspect you didn't
try the test suite yet? I fixed that particular problem, but now with your
patch applied I get this:
$ ./src/curl -V
curl 7.20.2-DEV (i686-pc-linux-gnu) libcurl/7.20.2-DEV GnuTLS/2.8.5
zlib/1.2.3.4 libidn/1.15
Protocols: dict file ftp ftps http https imap imaps ldap pop3 pop3s rtsp smtp
smtps telnet tftp
Features: Debug TrackMemory IDN IPv6 Largefile NTLM SSL libz
$ cd tests
$ ./runtests -g 305
