Are you sure it's legal to take "< 3" and paste on the remaining characters, e.g., "0404"? My knowledge of the preprocesor is pretty limited, but this sounds like something Paul M. told me was undefined.
Missed this. It isn't undefined. The operands of the token-pasting operator are only the two tokens immediately adjacent to it. However, if one of these operands is part of an argument, it has the effect of disabling argument expansion for the entire argument. I.e. it acts only on two tokens, but it affects expansion of the entire argument. Regards, Paul Mensonides
