Subject: [PATCH] Fix test_tarfile failures on Alpha (Tru64).  The problem was
 caused in r61449 which made the return value signed.  On the Alpha that also
 lost data since sizeof(int) != sizeof(long) and apparently adler32/crc32
 return 64 bits of data.  This change keeps the signedness and continues to
 store the data in a long rather than an int as was the case before r61449.
