--- Comment #7 from Pavel M <pavel.morozkin at gmail dot com> ---
Macros don't have file scope. The scope of macro definitions is defined in =
C11,
6.10.3.5.

The program in comment 4 defines a non-reserved identifier as a macro name,=
 and
is therefore valid.

P.J. Plauger, Standard C Library Name Space Control, JCLT, 1(4), page 251:
> Remember that the user can write macros that begin with an underscore, fo=
llowed by a lowercase letter.
