Google Code Search finds many copies of des.h, where the DES_KEY_SZ macro is defined. It’s the size of a des_cblock, which happens to be an array of eight unsigned chars.

In other words, DES_KEY_SZ = 8.

You’re going to run into other problems beyond just that missing identifier, though. The code you showed calls a handful of DES functions, too. To unencrypt the data, try using DCPCrypt.
