Ohh.. I wasn't aware about this case, since I get no errors at all at this line. Do you see any others?
As Tim explains, this is likely due to me using a more recent gcc (3.3). I'll attach my current list of warnings below. The signed/unsigned warnings are actually harmless: they cause a problem only when comparing negative and unsigned numbers (where the negative number gets converted to unsigned and may actually compare larger than the positive one). This should not be an issue for SRE - I believe all the numbers are always non-negative, unless they are the -1 marker (for which I'm uncertain whether it is ever relationally compared).
