 Adding '#include <stdint.h>' to tm.h fixes this problem.

 Reported by Po-Ching:

 By the way, we find the TM always gets a segmentation fault if
 we set the 'mem' option to a small value, say 20k. The segmentation
 fault does not appear if this option value is large, say 200k.
 Following is the debugging session with gdb for your reference.
 The segmentation fault may sometimes occur in pthread_join in main.cc:847,
 or pthread_create in main.cc:813 or main.cc:763. Our system is Fedora
 Linux 12. Please let us know if you don't reproduce the same problem in
 your environment.  Thanks a lot::

#8: Filesize issues
-------------------------------------------------+-------------------------

 Cut and paste from several emails describing the problem:

 * With filesize set at exactly 280g (279g does not produce the problem)
   tm will create one disk fifo file per packet in the workdir for each
   evicted packet with a disk setting of 1000g.  I am only using one
   default class for "all."

 * That sounds like something is wrapping and going negative at
   the 2^38 barrier.

 * Further testing shows that filesize > 2000m (including 2g for
   some reason) leads to tm not rolling the file ever.
