Hi Gregg,

I wanted to get back to you on this problem.

First, I will be unable to test this on an HPUX 10.20 after all.  Like I said, 
we don't have one in house, we have to borrow one on a temporary basis.  
Although we do provide some HPUX 10.20 support for the NWS, officially we only 
support HPUX 11.0.

But, I do have a bit of info that may be of some help.  Turns out that c89 and 
cc are the same.  We suspect that the code sets some environment variables 
based on the whether the code was called via 'c89' or 'cc'.  

The only reason I can guess that you got these results is that perhaps c89 uses 
the extended ANSI mode (-Ae).  Otherwise I don't see any other relevant 
variables among the ones you listed above.

I'm sorry, but that's the best I can do for you at this point.   I'm glad your 
LDM is indeed running.  If you do find out what the problem was I'd be 
interested to hear it.

Please contact us if you have any more questions.

Anne
