// - When the filename is enclosed in double quotes ("filename"), for
// a relative path the compiler’s current working directory, and
// optionally user-specified locations are searched.
// - When the filename is enclosed in angle brackets (<filename>), then
// only an implementationdependent location containing files defined

// In this implementation, filenames enclosed in angle brackets are
