It's not clear to me which MDAC package I should be downloading to get SQLLEN defined in the headers/libs. Do you know which you're using?
I take it back.
MDAC 2.8 SDK looks like the right one:

My machine doesn't validate as 'Genuine Windows' and never has, despite the fact that it's an IBM laptop with XP pre-installed. So if anyone could manually get the relevant headers/libs to me I'd be very grateful.
Thanks,
