My understanding was double underscore identifiers are reserved for implementation
(C99 7.1.3 Reserved identifiers).

Yes, and that's the point. When this code is used as part of Gnulib, it is usedwithin an application, so any identifiers it uses that start with __ mightcollide with the implementation, which means it's safer to avoid them when it'seasy, as is the case here.
