No, I can do 2**32 and much higher. Apparently, the limit on my
system is sys.maxint (which is *really big*)
>>> import sys
Traceback (most recent call last):
File "<stdin>", line 1, in ?
OverflowError: long int too large to convert to int
I suddenly realize what is going on. The CPU, the AMD Opteron 250, is
a 64 bit processor. I just got this machine and didn't know what kind
of CPU it had.
Apparently, on 64bit systems, tell returns an int because an int can
address 2**63 bytes. So the acid test in the 64 bit era for LFS is to
try and seek to 2**31, not to check the return type of tell.
