‘uint64_t’ does not name a type

Building on Ubuntu server 10.04.1 LTS, I get:

In file included from Connections.hh:42,
from Connections.cc:37:
tm.h:55: error: ‘uint64_t’ does not name a type
tm.h:56: error: ‘uint64_t’ does not name a type
tm.h:57: error: ‘uint64_t’ does not name a type
tm.h:58: error: ‘uint64_t’ does not name a type
tm.h:59: error: ‘uint64_t’ does not name a type
tm.h:60: error: ‘uint64_t’ does not name a type
make[1]: *** [Connections.o] Error 1
make[1]: Leaving directory `/home/sroddy/tm-20090206'
make: *** [all] Error 2

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