Why are MQCNO_HANDLE_SHARE_... constants excluded?

[d11wtq]

I'm trying to use WMQ in a multi-threaded Ruby environment. While I can do this fine provided I open and close connections within the same thread, I cannot sensible structure my code around e.g. Connection Pooling.

I see that WMQ itself does support multi-threaded environments, with MQCNO_HANDLE_SHARE_BLOCK, but since GenerateConst explicitly excludes the HANDLE_SHARE options, it's not available out of the box.

I have manually tested with the value of MQCNO_HANDLE_SHARE_BLOCK and everything works as expected (at least from what I can see) and this resolves a whole lot of issues for me. Is there a strong reason why this constant has been excluded, or is it a mistake, or untested?

I'm reluctant to copy and paste the value into our code, since it may change if cmqc.h is updated in a future release.
