I think this happens because z_abs is defined in libf2c and libm (or
libc?) on your system.  Removing the object from one or the other of
the libraries will probably solve your problem, though you should
probably check to make sure that they really are the same (i.e., find
the source for both libraries and see if both functions are supposed
to do the same thing).  This problem should probably be reported to
the Mklinux maintainers.
