Preprocessing directives
- How sequences in both forms of header names are mapped to headers
or external source file names (6.4.7).
- Whether the value of a character constant in a constant expression
that controls conditional inclusion matches the value of the same character
constant in the execution character set (6.10.1).
- Whether the value of a single-character character constant in a
constant expression that controls conditional inclusion may have a
negative value (6.10.1).
- The places that are searched for an included
<>
delimited
header, and how the places are specified or the header is
identified (6.10.2).
- How the named source file is searched for in an included
""
delimited header (6.10.2).
- The method by which preprocessing tokens (possibly resulting from
macro expansion) in a
#include
directive are combined into a header
name (6.10.2).
- The nesting limit for
#include
processing (6.10.2).
- Whether the
#
operator inserts a \
character before
the \
character that begins a universal character name in a
character constant or string literal (6.10.3.2).
- The behavior on each recognized non-
STDC #pragma
directive (6.10.6).
- The definitions for
__DATE__
and __TIME__
when
respectively, the date and time of translation are not available (6.10.8).
