-@c Options affecting preprocessor warnings
-@c ---------------------------------------------------------------------
-
-@c If this file is included with the flag ``cppmanual'' set, it is
-@c formatted for inclusion in the CPP manual; otherwise the main GCC manual.
-
-@item -Wcomment
-@itemx -Wcomments
-@opindex Wcomment
-@opindex Wcomments
-Warn whenever a comment-start sequence @samp{/*} appears in a @samp{/*}
-comment, or whenever a backslash-newline appears in a @samp{//} comment.
-This warning is enabled by @option{-Wall}.
-
-@item -Wtrigraphs
-@opindex Wtrigraphs
-@anchor{Wtrigraphs}
-Warn if any trigraphs are encountered that might change the meaning of
-the program.  Trigraphs within comments are not warned about,
-except those that would form escaped newlines.
-
-This option is implied by @option{-Wall}.  If @option{-Wall} is not
-given, this option is still enabled unless trigraphs are enabled.  To
-get trigraph conversion without warnings, but get the other
-@option{-Wall} warnings, use @samp{-trigraphs -Wall -Wno-trigraphs}.
-
-@item -Wundef
-@opindex Wundef
-@opindex Wno-undef
-Warn if an undefined identifier is evaluated in an @code{#if} directive.
-Such identifiers are replaced with zero.
-
-@item -Wexpansion-to-defined
-@opindex Wexpansion-to-defined
-Warn whenever @samp{defined} is encountered in the expansion of a macro
-(including the case where the macro is expanded by an @samp{#if} directive).
-Such usage is not portable.
-This warning is also enabled by @option{-Wpedantic} and @option{-Wextra}.
-
-@item -Wunused-macros
-@opindex Wunused-macros
-Warn about macros defined in the main file that are unused.  A macro
-is @dfn{used} if it is expanded or tested for existence at least once.
-The preprocessor also warns if the macro has not been used at the
-time it is redefined or undefined.
-
-Built-in macros, macros defined on the command line, and macros
-defined in include files are not warned about.
-
-@emph{Note:} If a macro is actually used, but only used in skipped
-conditional blocks, then the preprocessor reports it as unused.  To avoid the
-warning in such a case, you might improve the scope of the macro's
-definition by, for example, moving it into the first skipped block.
-Alternatively, you could provide a dummy use with something like:
-
-@smallexample
-#if defined the_macro_causing_the_warning
-#endif
-@end smallexample
-
-@item -Wno-endif-labels
-@opindex Wno-endif-labels
-@opindex Wendif-labels
-Do not warn whenever an @code{#else} or an @code{#endif} are followed by text.
-This sometimes happens in older programs with code of the form
-
-@smallexample
-#if FOO
-@dots{}
-#else FOO
-@dots{}
-#endif FOO
-@end smallexample
-
-@noindent
-The second and third @code{FOO} should be in comments.
-This warning is on by default.
