Explicitely cast NumConnections etc. (size_t) to "long"

This fixes the following compiler warning, for example on OpenSolaris:

  conn.c: In function 'Conn_Handler':
  conn.c:798:28: warning: format '%ld' expects argument of type 'long int',
    but argument 4 has type 'size_t' {aka 'unsigned int'} [-Wformat=]
