Thanks for the in-depth responses and feedback.

When reinvestigating this in more detail that led me to create this patch, I discovered that the premise upon which I was operating upon was not the default (desired) compiler and linker flags.  It turns out the environment I am working in builds all of the software using -bsvr4 and -brtl on AIX.

I have a lot more to unravel now.  I already closed the PR and will abandon this issue since it has been clearly illustrated that this is masking an underlying problem.

Thanks for taking the time to provide feedback and detail of what is problematic with this change.
