g_module_build_path on Win32

[Eugene T <gtkplist talagrand org>]

Hi,
	g_module_build_path prepends a "lib" prefix to module names on Win32, 
which imitates the Unix behavior. Is there a technical reason for this? 
The gmodule changelog from 2001-10-09 hints that this was done to work 
around a bug in gdk-pixbuf-io, but this prevents the function from
loading general purpose dll's in a cross-platform way without
reproducing the logic. Shouldn't the fix reside in gdk-pixbuf-io?

Thanks,
Eugene
