NRLink-RCX-Communication.nxc from http://www.mindsensors.com/index.php?module=documents&JAS_DocumentManager_op=viewDocument&JAS_Document_id=72 fails to compile with b35 with nonsensical error messages , it builds successfully with b34
The mindsensors code is out of date. They need to update it to work with b35 which includes API functions in the standard header files for this device. The problem is that their functions have the same name as preprocessor macros in the b35 header files. If you rename the functions in their sample code then it will compile just fine.
