The cf2 flag exists and we are using the next unused bit as defined in 
ioparm.def. No previous version of the frontend or the runtime library use or 
look at this bit so there will be no compatibility issues.

I named the stream pointer iqstream to avoid it being color highlighted. My 
editor highlights "stream" has a "C" key word.

I will change the constant parameter IOPARM_INQUIRE_HAS_STREAM to 
IOPARM_INQUIRE_HAS_IQSTREAM just for consistency so that in the future, 
maintainers will know it is related to the use of the iqstream pointer.

I will commit the patch later today and thanks for the review.

Jerry
