+Please do not be surprised if MinGW produces a statically-linked minimal executable of 1 MB. Firstly, gcc
+produces larger executables than some compilers. Secondly, this figure will
+include most of the overhead of wxWindows, so as your application becomes more
+complex, the overhead becomes proportionaly less significant. And thirdly, trading executable compactness
+for the enormous increase in productivity you get with wxWindows is almost always well worth it.

 There is a sample which demonstrates MFC and wxWindows code co-existing in the same
 application. However, don&#39;t expect to be able to enable wxWindows windows with OLE-2
 functionality using MFC.<P>

+If you get errors like
+<p>
+<center>
+<tt>no matching function for call to &#39;wxDC::DrawTextA(const char[5], int,
+int)&#39;</tt>
+</center>
+<p>
+or similar ones for the other functions, i.e. the compiler error messages
+mention the function with the <tt>&#39;A&#39;</tt> suffix while you didn&#39;t
+use it in your code, the explanation is that you had included
+<tt>&#60;windows.h&#062;</tt> header which redefines many symbols to have such
+suffix (or <tt>&#39;W&#39;</tt> in the Unicode builds).
+
+<p>
+The fix is to either not include <tt>&#60;windows.h&#62;</tt> at all or include
+<tt>"wx/msw/winundef.h"</tt> immediately after it.
