Compile Error in PCInt

I'm trying to use the Arduino Playground - PcInt code and getting the below errors when I try and compile in the IDE (build 0016) on a Duemilanove 328.

error: expected constructor, destructor, or type conversion before string constant In function 'void PCattachInterrupt(uint8_t, void (*)(), int)':
In function 'void PCdetachInterrupt(uint8_t)':
In function 'void PCint(uint8_t)':

Any suggestions?
