You have found _different_ problems. One is that sockets.fas is not linked
in your program because you probably use (REQUIRE :sockets). Why not list
it as a dependency on your ASDF file?

The other one is the DLL issue, which arises because (as some other people
asked here in the mailing list) ECL does not have support for building
statically linked executables in Windows. It is not impossible: the code is
in the core, but the Makefile has not been adapted.

Change the system directory using setenv("ECLDIR","whatever/path/you/want")
before calling cl_boot().

This is just SBCL's sockets, ported to ECL. I do not know whether they
provide some documentation.
