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])

no translations for the weekday names in the program message catalog and
wxGetTranslation wouldn't find them.

For the second function (taking a string mask), the message is logged only if
the mask has been previously enabled by the call to
-\helpref{AddTraceMask}{wxlogaddtracemask}. The predefined string trace masks
-used by wxWindows are:
+\helpref{AddTraceMask}{wxlogaddtracemask} or by setting
+\helpref{{\tt WXTRACE} environment variable}{envvars}.
+The predefined string trace masks
+used by wxWidgets are:
\begin{itemize}\itemsep=0pt
\item wxTRACE\_MemAlloc: trace memory allocation (new/delete)
\item wxTRACE\_OleCalls: trace OLE method calls (Win32 only)
\end{itemize}

+{\bf Caveats:} since both the mask and the format string are strings,
+this might lead to function signature confusion in some cases:
+if you intend to call the format string only version of wxLogTrace,
+then add a \%s format string parameter and then supply a second string parameter for that \%s, the string mask version of wxLogTrace will erroneously get called instead, since you are supplying two string parameters to the function.
+In this case you'll unfortunately have to avoid having two leading
+string parameters, e.g. by adding a bogus integer (with its \%d format string).
+
+The third version of the function only logs the message if all the bits
corresponding to the {\it mask} are set in the wxLog trace mask which can be
set by \helpref{SetTraceMask}{wxlogsettracemask}. This version is less
flexible than the previous one because it doesn't allow defining the user
