*** Error code 1

Stop.
>How-To-Repeat:
Just make Apache 1.3.6 with *no* SSL or other additional modules on Ultrix 4.4.
>Fix:
No, but you guys have seen this before as PR 958 (now closed). For that PR, rtt@synapse.net
said "Without access to various ultrix platforms it'll be hard to
eliminate the warnings reliably.  So for now we'll just have to live with them."

So here is the result on another Ultrix platform at a different Apache release. 

Please ignore the failure in "ar" at the end of the above trace - I'll log that as a separate
PR.

Sorry if there's nothing you can do - please just close this PR. But I'd appreciate knowing
whether or not the warnings "matter". Or even whether you think I'd get a clean(er) build
if I used GCC instead of DEC's compiler.
