It's a pp-number (they came up recently in another thread). If it gets used as a number it will result in a error. Likewise if it gets used as an identifier. The syntax for pp-token breaks the input up into tokens using very simple rules. These are shuffled about by the pre-processor and the tokens are sometimes interpreted as having a meaning (as, for example, and identifier or a number). In the example you gave, the token 1_0 is simply glued onto another token to make an identifier. <snip> -- Ben.
