--- Comment #69 from Manuel König <manuelk89 at gmx.net> ---
I hit this 15 years old bug again, and now feel very insecure about the
correctness of all integer comparisons in all my code. At least a warning about
signed-unsigned comparison would be great, doing the mathematically correct
fast & safe integer promotions would be even better. Not sure how to deal with
the slower comparisons like long-unsigned that have no direct assembly
comparison instruction, maybe just produce an error message.
