System Workbench for STM32

This looks to be a part of the answer to the questions I've posted here:

This explains why the cc1 doesn't work even though the path appears correct!

While I can make the path change to the 64 bit version of the tools that I have downloaded, I'd like to do it globally. However, the capability appears to be missing from Eclipse now. Specifically, I cannot find the entry Preferences -> C/C++ -> Build -> Global Tools Paths. Has that been removed?

A related question: Is the modified version of OpenOCD a 32 bit version also? If so, how soon can we expect a proper, usable 64 bit version?

Thanks for your help!
