Sometimes, there might be more than one object that resolves a
specific symbol. If you take one out, the other gets used, and that
changes everything.
For example, DJGPP has two math libraries. One (libm.a) has a
complete set of conforming (but slightly slower) functions, and the
other (in libc.a) is smaller and faster, but less complete and less
conforming. If you link in libm.a, you get that set, but if you leave
it out, the ones in libc.a get used.
