From 0f92f7352d1964a9859868439e8ded2c4de2111e Mon Sep 17 00:00:00 2001 From: Rory Bradford 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).
