Well, sure, and the fact that the linker *gives* you that second chance. 
Most linkers will fail if there are unresolved symbols, so in that 
sense, Linux ld is more forgiving. The order issue is that if you 
specify the lib before the object, it doesn't know what to import from 
the lib (but I think it stills makes a note that that lib should be 
loaded, no?).
