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).”
<install directory>/lib/gcc/pic32mx/3.4.4/include
<install directory>/pic32mx/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, the directories specified by the
-iquote command line option (if any), 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.
“The behavior on each recognized non- STDC #pragma directive
(C90 6.8.6, C99 6.10.6).”
“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).”
The date and time of translation are always available.
