Syntax question

I recently downloaded CodeWarrior to start on a project for a MC9S12XDP512. While I was looking through MC9S12XDP512.h, I came across this line (21322):


extern volatile DDRSSTR _DDRS @(REG_BASE + 0x0000024AUL);


I've never seen the @ character used in this way in C, and I haven't found a search engine that indexes '@', so I can't search for information. Is this a custom addition to CodeWarrior's C or preprocessor syntax?
