Wrapping atexit() is a bad idea on Windows, where the EXE and each DLL

	* glib/gutils.h: Wrapping atexit() is a bad idea on Windows, where
	the EXE and each DLL have their own atexit function chains.

	#define g_atexit as atexit instead. This means it has a
	better chance of doing what the caller wants. For instance,
	gtkhtml calls g_atexit() registering a function in gtkhtml
	itself. This caused a crash when g_atexit() was implemented as a
	function in the GLib DLL. The gtkhtml DLL was already unloaded by
	the time the GLib DLL got unloaded.

	* glib/gutils.c: #undef the #define mentioned above, to also get a
	real g_atexit() into the DLL for backward compatibility.
