FYI: fix for wierd ZSERVER.LIB errors

Hi, I’m busy adding a web server to an existing project (moving from RCM2300 to RCM2200).
I got ZSERVER.LIB errors when compiling. They were caused by 2 defines in my code: open & close, which I guess are used elsewhere. Took a day to find. There were no warnings that open & close were already defined!

After changing the names, the code compiles OK.
