<p>
<p>
All the identifiers defined in this specification that have external
linkage are always reserved for use as identifiers with external linkage.
<p>
No other identifiers are reserved.
<p>
Applications must not declare or define identifiers with the same name as an
identifier reserved in the same context. Since macro names are replaced
whenever found, independent of scope and name space, macro names matching any
of the reserved identifier names must not be defined if any associated header
is included.
<p>
Except that the effect of each inclusion of
<i><a href="assert.h.html">&lt;assert.h&gt;</a></i>
depends on the definition of NDEBUG, headers may be included
in any order, and each may be included more than once in a given scope,
with no difference in effect from that of being included only once.
<p>
If used, a header must be included outside of any external declaration
or definition, and it must be first included before the first reference
to any type or macro it defines, or to any function or object it declares.
However, if an identifier is declared or defined
in more than one header, the second and subsequent associated headers
may be included after the initial reference to the identifier.
Prior to the inclusion of a header,
the program must not define any macros with names lexically identical
to symbols defined by that header.
