The code is only a 'snippet'... Basically, there should be a variable defined calld 'cSkip', which is presumably set true, when characters are not to be displayed (skipped). Try adding:
int1 cSkip=false;
Near the definitions at the front of the code. Also be aware that you are going to have to include the processor file etc., before the port definitions will work.
You really need to ask to ask the author about what else is needed. You could instead just use the lcd.h include file that comes with the compiler, and change a couple of definitions to suit your port, and for this you will find a lot more people with knowledge/experience here.
