Why not take the same route as GNU libiconv? The eglib headers could  
#define GLib symbols to have a mono_ prefix, distinguishing them from  
any real GLib symbols that might get linked in somewhere. Mono's  
runtime code would then not need to be touched and one could still  
choose to link against original GLib.
