// This function is used to create a path to a file, given the directory name
// and the filename within the directory. This sounds pretty trivial (and is!)
// but it does two things that are important:
// It uses the correct path separator for the operating system, and it handles the cases
// of the source directory being "". In particular, it
// makes sure that if the directory is "" then the full path turns into "filename" rather
// than "/filename". On return it points to a buffer that contains the full path, and
// which is overwritten on every call to this function.
