Before the unary minus, the compiler first evaluates the literal, which is larger than the maximum allowed integer and results in a warning. To correctly get the value for INT64_MIN, we substract from one number larger. See https://en.cppreference.com/w/cpp/language/integer_literal. Also adding missing integer suffixes for generated C code. Signed-off-by: Jacob Perron <jacob@openrobotics.org>
