Note that the single-leading-underscore reservation is for the global namespace.

Only under the second bullet point is the global namespace mentioned. The first bullet point which also covers cases as '_X' says reserved for "any use". It might work for private members but does not have to.

The case I referred to actually caused an error at class scope (see here for the change and here for the errors the name caused).

(While we're on the topic of collisions, I ran into one when porting Eigen to AVR: the use of B0, etc. as template parameters collided with the unfortunate use of them as preprocessor macros for binary.

I would change the occurrences of such types/typedefs and provide more descriptive names. It should be easier to read and reduce the chances of collisions.
