digitalWriteFast: compiling error

Hi Nick, hi everybody,
unfortunately yes, I restarted my IDE.

I also just restarted my computer and I got the same error message:

Blink_with_digitalWriteFast.cpp: In function 'void loop()':
Blink_with_digitalWriteFast:9: error: invalid type argument of 'unary *'
Blink_with_digitalWriteFast:11: error: invalid type argument of 'unary *'

I know this is weird, as I also expected it to work.

Can it have something to do with my operating system???
I am currently working with Windows XP.
