+other language. It takes two extra arguments: \arg{str}
+parameter must contain the singular form of the string to be converted.
+It is also used as the key for the search in the catalog.
+The \arg{strPlural} parameter is the plural form (in English).
+The parameter \arg{n} is used to determine the plural form. If no
+message catalog is found \arg{str} is returned if `n == 1',
+otherwise \arg{strPlural}. The \helpref{ngettext}{ngettext} macro is defined
+to do the same thing.

translated (note that it is a bad example, really, as
\helpref{wxDateTime}{wxdatetime} already can be used to get the localized week
day names already). If you write
+
\begin{verbatim}
static const wxChar * const weekdays[] = { _("Mon"), ..., _("Sun") };
...
// use weekdays[n] as usual
\end{verbatim}
+
the code wouldn't compile because the function calls are forbidden in the array
initializer. So instead you should do
+
\begin{verbatim}
static const wxChar * const weekdays[] = { wxTRANSLATE("Mon"), ..., wxTRANSLATE("Sun") };
...
// use wxGetTranslation(weekdays[n])
\end{verbatim}
+
here.

For the second function (taking a string mask), the message is logged only if
the mask has been previously enabled by the call to

used by wxWindows are:
\begin{itemize}\itemsep=0pt
either change the line in which either of them appears on or use the
\helpref{wxCOMPILE\_TIME\_ASSERT2}{wxcompiletimeassert2} macro.
+Also note that Microsoft Visual C++ has a bug which results in compiler errors
+if you use this macro with ``Program Database For Edit And Continue''
+(\texttt{/ZI}) option, so you shouldn't use it (``Program Database''
+(\texttt{/Zi}) is ok though) for the code making use of this macro.
