4094 shift register with lcd to reduce pins

I wanted to use less pins in arduino to connect arduino hebce followed this post Arduino Playground - LCD3wires which requires me to use WConstants.h also i can't use Arduino.h or wiring.h So, is there anyone who can provide me WConstants.h file. It was being used in earlier versions of arduino before 1.0 like 0019, 0023 etc. Plz help. It's urgent. Thanks

That file is not needed anymore. All the constants that were in that file are now in Arduino.h
