+================================================================================
+BEWARE: The current implementation pokes I/O ports to access the PCI devices
+directly. This leads to several problems: some devices are invisible, extended
+PCIe configuration space is not available, and there are many potential race
+conditions. Instead, libpci should use the proper Windows drivers.
+
+Unfortunately, the Windows port currently lacks a maintainer. If you are willing
+to step up and fix the issues, please let me know. -- Martin Mares
