It looks to me like there are four commands that get issued to compile the testcase. We need to narrow it down to what command fails and exactly where in the dejagnu code it is issued from and where the error is "detected". I haven't debugged dejagnu code in the past so this could be interesting. I will look to see about turning on vebose -log to see what I can get from it. Thanks for mentioning that. Carl
