Make File in Informix -- please help!!!!!

Hello, everyone I installed informix-ESQL/C 7.23 TC1 (Released on 4/29/97) and informix-cli 2.5.TD2 (released on 2/14/97) on my Windows NT workstation under the same directory c:\\program files\\informix. I could not run the .make files (either the demo or my own .make files). The following is the error message when I run my own make file named 'historylib': -----Start of message----- Microsoft (R) Program Maintenance Utility Version 1.62.7022 Copyright (C) Microsoft Corp 1988-1997.
