Hi Markus,
The latest patch works fine even without c-ares for ip and hostname. And
the bind failure for bge0 is more informative as given below;

testsvr% curl --verbose --interface bge0 --local-port 60027-60028
https://10.20.4.19/cgi-bin/TEST/TEST.py
* About to connect() to 10.20.4.19 port 443 (#0)
* Trying 10.20.4.19... getaddrinfo(3) failed for bge0:0
* Couldn't bind to 'bge0'
* couldn't connect to host
* Closing connection #0

Thanks for all the support.
Senthil.

I've been able to verify it works on Solaris 8 SunOS 5.8
Generic_117350-44 sun4u sparc SUNW,Ultra-60 Solaris without c-ares.

Curl on Solaris does not support --interface with a real interface, such
as bge0.

Why did it work with unpatched curl in the same network on the same
machine? I don't know.
I have no idea how solaris resolver behaves if there is no dns server
(reachable).

Hopefully the last version of the patch is attached.
Removes socket_domain, as it is not used, fixes > * Couldn't bind to ''
if the dev could not be recognized as interface/domain/ip, and does not
try to connect a different/non equal af.

Please retry.

This time the patch is created different:

diff -Naur curl-7.19.4-20090219.orig/lib/connect.c
curl-7.19.4-20090219/lib/connect.c >
/tmp/curl_interface_and_port_patch-hopefully_the_last.diff
