From 0f92f7352d1964a9859868439e8ded2c4de2111e Mon Sep 17 00:00:00 2001
From: Rory Bradford <roryrjb@gmail.com>
Date: Sat, 19 Nov 2022 11:11:26 +0000
Subject: Full native win32 support

This will now compile with MSVC using the make.bat batch file. It does
however bring in some additional third party dependencies: ports of
dirent and getopt (something I'd ideally like to work on in the future).
