Bug 98479

 I had the file of big size (2G byte over) can read.
 At present, the problem doesn't occur in my environment. However, it is not division that tests everything.
 The agreement of cd9660 to the standard is not investigated. However, I thought that there is especially no problem because it is only reading.
 I changed to the source of 6.1-RELEASE.
