+# Makefile.win - cross-compile the Windows build with mingw-w64.
+#
+# Links the Win32 backend instead of the Wayland one (no protocols, no
+# wayland-scanner, no pkg-config). Produces a single static mouseboard.exe.
+#
+#   make -f Makefile.win                              # x86_64
+#   make -f Makefile.win CC=i686-w64-mingw32-gcc      # 32-bit
+#
+# Needs a mingw-w64 cross toolchain on the build host:
+#   Debian / Ubuntu : sudo apt install gcc-mingw-w64-x86-64
+#   Arch            : sudo pacman -S mingw-w64-gcc
+#   Fedora          : sudo dnf install mingw64-gcc
+#
+# Built for the GUI subsystem (-mwindows) so launching it - e.g. from a hotkey -
+# creates no console window. The backend still calls AttachConsole() at startup,
+# so --help / --dry-run / --selftest output appears when run from a terminal.
