Description
The cygdb documentation still refers to Python 2, whereas most Linux distributions probably have switched to Python 3 by default these days and also provide gdb for that version. Ubuntu has definitely done this for years.
We should move all "build your own gdb" stuff to the end, for users who really need to make it work with a different Python version than their system provides, and help users making it work in the normal Python 3 + "just install some packages" case again.
