Something else you may want to try, if you used Wind River last year is to uninstall it and delete all traces of it. Then reinstall, I think the location of WPILib.a moved down a directory and Wind River could be pointing to the wrong file.

You may also try searching for WPILib.a under C:\Windriver and deleting it, after that reinstall the Workbench update. If it can't find WPILib.a then that's your issue and you need to point to the current location. If you were using WPILIb source code to compile you WPILib.a file that can cause the issue as well. I haven't seen the new version of WPILib source yet.
