Unable to build application if "UNICODE" macro is defined

[cmhxone]

If "UNICODE" macro is defined, compiler unabled to find argv identifier.

My short-sighted opinion is rename wargv argument to argv...

SDL/include/SDL3/SDL_main_impl.h

Lines 65 to 74 in 5a2a91c

	#if defined( UNICODE ) && UNICODE
	int wmain(int argc, wchar_t *wargv[], wchar_t *wenvp)
	#else /* ANSI */
	int main(int argc, char *argv[])
	#endif
	{
	(void)argc;
	(void)argv;
	return SDL_RunApp(0, NULL, SDL_main, NULL);
	}

It'll also need:

#if defined(UNICODE) && UNICODE
    (void)wenvp;
#endif

to avoid a warning about a unused wenvp.
