| “How sequences in both forms of header names are
mapped to headers or external source file names (C90 6.1.7, C99
6.4.7).” |
|
The character sequence between the delimiters is considered to be a string
which is a file name for the host environment. |
| “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 (C90 6.8.1, C99
6.10.1).” |
|
Yes. |
| “Whether the value of a single-character character
constant in a constant expression that controls conditional inclusion may have
a negative value (C90 6.8.1, C99 6.10.1).” |
|
Yes. |
“The places that are searched for an included
< > delimited header and how the places are specified
or the header is identified (C90 6.8.2, C99 6.10.2).” |
|
The preprocessor searches any directory specified using the
-I option, then, provided the -nostdinc
option has not been used, the standard compiler include directory,
<install directory>/pic/include |
“How the named source file is searched for in an
included " " delimited header (C90 6.8.2, C99
6.10.2).” |
|
The compiler first searches for the named file in the directory containing
the including file, then the directories which are searched for a <
> delimited header. |
| “The method by which preprocessing tokens are
combined into a header name (C90 6.8.2, C99 6.10.2).” |
|
All tokens, including whitespace, are considered part of the header file
name. Macro expansion is not performed on tokens inside the delimiters. |
“The nesting limit for #include
processing (C90 6.8.2, C99 6.10.2).” |
|
No limit. |
“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).” |
|
No. |
“The behavior on each recognized non-STDC
#pragma directive (C90 6.8.6, C99 6.10.6).” |
|
See the section on Pragma Directives. |
“The definitions for __DATE__ and
__TIME__ when respectively, the date and time of
translation are not available (C90 6.8.8, C99 6.10.8).” |
