+// (2) You should link with MFC DLL, not static libraries: or, to use static
+//     run-time libraries, use this command for both building wxWidgets and
+//     the sample:
+//
+//     nmake -f makefile.vc BUILD=debug SHARED=0 DEBUG_RUNTIME_LIBS=0 RUNTIME_LIBS=static all
+//
+//     Unless the run-time library settings match for wxWidgets and MFC, you
+//     will get link errors for symbols such as __mbctype, __argc, and __argv 
+//
+// (3) If you see bogus memory leaks within the MSVC IDE on exit, in this
+//     sample or in your own project, you must be using __WXDEBUG__ +
+//     WXUSINGDLL + _AFXDLL
+//     Unfortunately this confuses the MSVC/MFC leak detector. To do away with
+//     these bogus memory leaks, add this to the list of link objects, make it
+//     first: mfc[version][u]d.lib
+//     -  [version] -> 42 or 70 or 80 etc
+//     -  u if using Unicode
+//
+// (4) Unicode builds may produce the linker error "unresolved external symbol _WinMain@16".
+//     MFC requires you to manually add the Unicode entry point to the linker settings,
+//     Entry point symbol -> wWinMainCRTStartup
