You didn't mention what gcc error you got. You need to give complete info about a problem if you want a good answer.

Since this is a very target dependent issue, you might try sending mail to a cyginw or mingw list. Gcc developers generally aren't Microsoft Windows experts.

I tried a quick web search, it seems the answer is that win32 doesn't support direct access to the I/O ports, so you can't do what you are trying to do without a device driver. If you want a better answer, you need to ask people who know more about MS Windows programming. -- Jim Wilson, GNU Tools Support, http://www.specifix.com
