+.IP "\fB\-fexec\-charset=\fR\fIcharset\fR" 4
+.IX Item "-fexec-charset=charset"
+Set the execution character set, used for string and character
+constants. The default is \s-1UTF\-8\s0. \fIcharset\fR can be any encoding
+supported by the system's \f(CW\*(C`iconv\*(C'\fR library routine.
+.IP "\fB\-fwide\-exec\-charset=\fR\fIcharset\fR" 4
+.IX Item "-fwide-exec-charset=charset"
+Set the wide execution character set, used for wide string and
+character constants. The default is \s-1UTF\-32\s0 or \s-1UTF\-16\s0, whichever
+corresponds to the width of \f(CW\*(C`wchar_t\*(C'\fR. As with
+\&\fB\-fexec\-charset\fR, \fIcharset\fR can be any encoding supported
+by the system's \f(CW\*(C`iconv\*(C'\fR library routine; however, you will have
+problems with encodings that do not fit exactly in \f(CW\*(C`wchar_t\*(C'\fR.
+.IP "\fB\-finput\-charset=\fR\fIcharset\fR" 4
+.IX Item "-finput-charset=charset"
+Set the input character set, used for translation from the character
+set of the input file to the source character set used by \s-1GCC\s0. If the
+locale does not specify, or \s-1GCC\s0 cannot get this information from the
+locale, the default is \s-1UTF\-8\s0. This can be overridden by either the locale
+or this command line option. Currently the command line option takes
+precedence if there's a conflict. \fIcharset\fR can be any encoding
+supported by the system's \f(CW\*(C`iconv\*(C'\fR library routine.
+.IP "\fB\-fworking\-directory\fR" 4
+.IX Item "-fworking-directory"
+Enable generation of linemarkers in the preprocessor output that will
+let the compiler know the current working directory at the time of
+preprocessing. When this option is enabled, the preprocessor will
+emit, after the initial linemarker, a second linemarker with the
+current working directory followed by two slashes. \s-1GCC\s0 will use this
+directory, when it's present in the preprocessed input, as the
+directory emitted as the current working directory in some debugging
+information formats. This option is implicitly enabled if debugging
+information is enabled, but this can be inhibited with the negated
+form \fB\-fno\-working\-directory\fR. If the \fB\-P\fR flag is
+present in the command line, this option has no effect, since no
+\&\f(CW\*(C`#line\*(C'\fR directives are emitted whatsoever.
