* os_win32.C (init): Add Ruurd's original code to close the
console window that Windows opens for us, together with a note
explaining the alternative approach.

/* 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.
