Interestingly I believe this is an error in the standard (referring to
the reference to 2.11). 2.11 is not about characters at all but about
keywords and makes no mention of upper/lower case. 2.10 contains text
mentioning significance of case. 2.13.2 is about character literals
but also does not mention case. There is no 17.2.11. My bet is that
is supposed to be 2.10 referring to:

"An identifier is an arbitrarily long sequence of letters and digits.
Each universal-character-name in an identifier shall designate a
character whose encoding in ISO 10646 falls into one of the ranges
specified in Annex E. Upper- and lower-case letters are different.
All characters are significant..."

It depends on the scope of the name. In global scope ANY name that
begins with an underscore is reserved. Other scopes anything that
begins with __ or with _ and an upper case letter. Your quote:

17.4.3.1.2 Global names

Certain sets of names and function signatures are always reserved to
the implementation:

-- Each name that contains a double underscore (__) or begins with an
underscore followed by an upper case letter (2.11) is reserved to the
implementation for any use.

-- Each name that begins with an underscore is reserved to the
implementation for use as a name in the global namespace. 165)

165) Such names are also reserved in namespace ::std (17.4.3.1)

Thanks.
