Returns the signedness of the given +type+. You may optionally specify additional +headers+ to search in for the +type+. If the +type+ is found and is a numeric type, a macro is passed as a preprocessor constant to the compiler using the +type+ name, in uppercase, prepended with 'SIGNEDNESS_OF_', followed by the +type+ name, followed by '=X' where 'X' is positive integer if the +type+ is unsigned, or negative integer if the +type+ is signed. For example, if size_t is defined as unsigned, then check_signedness('size_t') would returned +1 and the SIGNEDNESS_OF_SIZE_T=+1 preprocessor macro would be passed to the compiler, and SIGNEDNESS_OF_INT=-1 if check_signedness('int') is done.
