+/* Following definition aliases fopen to fopen64 on above mentioned
+ * platforms. This makes it possible to open and sequentially access
+ * files larger than 2GB from 32-bit application. It does not allow to
+ * traverse them beyond 2GB with fseek/ftell, but on the other hand *no*
+ * 32-bit platform permits that, not with fseek/ftell. Not to mention
+ * that breaking 2GB limit for seeking would require surgery to *our*
+ * API. But sequential access suffices for practical cases when you
+ * can run into large files, such as fingerprinting, so we can let API
+ * alone. For reference, the list of 32-bit platforms which allow for
+ * sequential access of large files without extra "magic" comprise *BSD,
+ * Darwin, IRIX...
