 ****************************************************************
 Routine TreeInsertMatch (in TCTREEP) had two problems. Host
 route subnetmasks were not handled properly, and the node
 field TreeNodeUpwardFromRight was not initialized.  When a new
 node is acquired, sometimes TreeNodeUpwardFromRight was already
 set to TRUE when we expected it to be FALSE.  If that condition
 occurs, our routing tree is incorrect, and assertion errors
 occur.
 
 PROBLEM CONCLUSION:
 The field TreeNodeUpwardFromRight is now initialized in
 TreeInsertMatch.  In addition, the routine was changed to
 correctly handle host routes subnetmasks.
