Don't enforce shared library build only on Windows. It might well make

	* configure.in: Don't enforce shared library build only on
	Windows. It might well make sense to build static libraries in
	some use cases.

	* glib/gutils.c: Don't compile the DllMain if building libglib
	statically. Also in that case don't return NULL from
	_glib_get_installation_directory(), but return the installation
	directory of the program's .exe file.
