+# build-win32.sh — Cross-compile native-hello for Windows using mingw64.
+#
+# Requirements:
+#   - x86_64-w64-mingw32-gcc (brew install mingw-w64)
+#   - elc in PATH or at ../../../lang/dist/platform/elc
+#
+# Output: build-win32/native-hello.exe
+#
+# Note: We use el_runtime_win32.c instead of el_runtime.c / el_seed.c because
+# those files have deep POSIX dependencies (pthread, curl, dlfcn, sys/socket,
+# etc.) that cannot be cross-compiled to Windows. el_runtime_win32.c provides
+# all the runtime symbols that native-hello and the el-native vessel actually
+# call, using only standard C11 + Win32 APIs.
