      I for one appreciate the hell out of cpp, because it allows me to maintain

Why ifdef's are a bad idea (reason #132):


How do you check your code for type-correctness and syntax-correctness in
the presence of many #ifdef's? Do you compile every possible combination
at least once?

various C compilers, not all combinations will necessarily be valid on each
