+// (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
