I received the following note concerning the "CodeGen" problem in IBM-MAIN a
while ago.
Can someone in IBM-MAIN, please create a PMR for this?
________________________________
Bill,
I apologize for the late reply.
Yes. please make a suggestion for a customer PMR in the IBM-MAIN list.
Again, thanks for your help.

RE: Fw: METAL C: CodeGen defeciency?
Would a customer PMR help? I can suggest it in the IBM-MAIN list - but won't
unless you think it would be useful.

Bill,
I won't say it was intentional. The same thing exists in non-Metal C
produced code too. And my digging shows that it has been in the compiler
since the z/OS V1R5 release. I'll have a chat with the compiler people here
to see how we want to deal with it.
Thnaks for bringing this to our attention.

See this post in IBM-MAIN.
Is this something that someone should create a PMR about - or is this
"intentional"? (I certainly don't know enough C to know the answer)
