As it turns out our test compiles add an OPT(0) after all programmer
supplied options "because that takes less CPU..." My comment that this
means that production programs are never the same as the ones that
have been tested was dismissed with a "We have done this for years
without anyone ever having a problem with it."

Submitting from SDSF with altered JCL does produce rather better code,
so I stand corrected (again, I'm losing it, rapidly...)

Apologies to all, at least for the z/OS part! However, I'm not going to
retract my remarks about the PL/I for Windows compiler.
