Sorry, if this reaches you twice. Looks like I accidentally sent this out yesterday with github-noreply.

The attached file `testtcp.scm` fails with gambit 0.9.2 here. With the attached patch applied it prints "Success!".

Another sorry: the patch is against 0.9.2 since I can't build current master using 0.9.3 (and can't use 0.9.3 with lambdanative for testing).

Otherwise the patch addresses the - to me at least surprising - fact that on my Linux box `sizeof(struct sockaddr)` is smaller than `sizeof(struct sockaddr_in6)`. Additionally it provides a sensible default for the local address to use with `open-tcp-client`.

Best

Jörg

BTW: After too many failed attempts like `make from-scratch` etc. I'd really love to learn how build githug/master.
