+ /* Note from Angus, 17 Jan 2005:
+ *
+ * The code below is taken verbatim from Ruurd's original patch
+ * porting LyX to Win32.
+ *
+ * Windows allows us to define LyX either as a console-based app
+ * or as a GUI-based app. Ruurd decided to define LyX as a
+ * console-based app with a "main" function rather than a "WinMain"
+ * function as the point of entry to the program, but to
+ * immediately close the console window that Windows helpfully
+ * opens for us. Doing so allows the user to see all of LyX's
+ * debug output simply by running LyX from a DOS or MSYS-shell
+ * prompt.
+ *
+ * The alternative approach is to define LyX as a genuine
+ * GUI-based app, with a "WinMain" function as the entry point to the
+ * executable rather than a "main" function, so:
+ *
+ * #if defined (_WIN32)
+ * # define WIN32_LEAN_AND_MEAN
+ * # include <stdlib.h> // for __argc,__argv
+ * # include <windows.h> // for WinMain
+ * #endif
+ *
+ * // This will require the "-mwindows" flag when linking with
+ * // gcc under MinGW.
+ * // For MSVC, use "/subsystem:windows".
+ * #if defined (_WIN32)
+ * int WINAPI WinMain(HINSTANCE, HINSTANCE, LPSTR, int)
+ * {
+ * return mymain(__argc, __argv);
+ * }
+ * #endif
+ *
+ * where "mymain" is just a renamed "main".
+ *
+ * However, doing so means that the lyxerr messages would mysteriously
+ * disappear. They could be resurrected with something like:
+ *
+ * #ifdef WIN32
+ * AllocConsole();
+ * freopen("conin$","r",stdin);
+ * freopen("conout$","w",stdout);
+ * freopen("conout$","w",stderr);
+ * #endif
+ *
+ * This code could be invoked (say) the first time that lyxerr
+ * is called. However, Ruurd has tried this route and found that some
+ * shell scripts failed, for mysterious reasons...
+ *
+ * I've chosen for now, therefore, to simply add Ruurd's original
+ * code as-is.
