Windows modules

I'm working on module support for Windows platforms. Many thanks to Andrew Begel for his help and for answering my onslaught of stupid questions. It does not quite work yet, but my long delayed adventure under the surgeon's knife will finally be happening tomorrow, so I'm going to be out of the picture for a short time. I thought I would share my progress before I disappear. The attached patch uses the explicit list technique (creation of a .DEF file listing all exported symbols), rather than the implicit technique (marking symbol definitions with __declspec(dllexport) or __declspec(dllimport) as necessary). The latter technique was proving too invasive in too many files. With this patch, the main binary builds and runs just fine, but the linking step for the modules fails with a bunch of undefined symbol errors. All of those symbols, however, are of the form *_iname or __nm__*. The GNU ld internals manual (ldint) says something about such symbols, but I have found it unintelligible. I don't yet know what I need to do to fix the problem, but I'll work on that when I return ... unless one of you has hit this problem before and can just tell me what to do, of course! So far I have only worked with Cygwin, but I'll tackle Mingw too once I get Cygwin support working. I won't be able to do anything with native Windows since I lack the necessary compiler.
