reserved identifier violation

[elfring]

I would like to point out that identifiers like “__PPMENU_H” and “__TV_H” do not fit to the expected naming convention of the C++ language standard.
Would you like to adjust your selection for unique names?

This pratice has been used by as since 90th last century. It's hard to change this tradition :)

How do you think about to avoid that this software depends on undefined behaviour?

[papyrussolution]

We use a double-underscore. I don't think it can cause some problems (i consider such a propability as very low). Nevertheless, i gratitude you, because i didn't know about that considaration (depends on undefined behaviour).

Can any misplaced underscores be deleted in affected identifiers?
