Hi Tom, thanks for your detailed and helpful response.
I know full well that log messages are there for a reason. My problem isn't just that I *want* to suppress log messages to stdout - it's that I *need *to (in release builds, at least). My programme uses curses, so if anything gets sent to stdout other than that which curses sends, it breaks the whole display. I wasn't aware that a minor change (i.e. literally just one character) would be enough to constitute license violation in practice (although yes, I suppose in principle it is). I do apologise; I normally try to be very careful to respect license terms. Anyway, I will now build with SDL support turned off and use fluid_set_log_function to suppress log messages. Thanks again for your help (and for creating this remarkable piece of software).
