I would not say that clang is broken or that the warning is unclear.
The flag is -Wformat-nonliteral and the warning message is "format
string is not a string  literal". I don't know how you can be more
clear and direct about the fact that the format string is not a string
literal. Looking at the code, we observe that clang is right (the
format string is indeed not a string literal). With the proper
function attributes, the compiler could do better checks and prevent
programming mistakes. Since clang pointed out this low-hanging fruit
improvement to gdb's code, why shouldn't we take advantage of it?

Anyway, Jack, you are welcome to submit a patch for this if you feel
like it and/or file a bug if it is not already done.
