We have not been able to reproduce this problem.
Can you identify which processor/OS you are using?

The missing symbol names look suspicious;
  .  they should not have a quote ' character at the end
  .  the N_ prefix should be FN_
  .  the F_ prefix should be CF_ 

It is possible that the problem is due to using a strange linker -
can you tell whether it is Gnu ld (via gcc) or some other linker?

One experiment that might fix the problem is to edit the script/nhc98.inst
shell script.  Line 530 is:

LDLIBS=$MAINROUTINE" "$NHC98LIBDIR/$MACHINE/mutlib$CFG.o" "$NHC98LIBDIR/$MACHINE/mutator$CFG.o" "$NHC98LIBDIR/$MACHINE/Prelude$CFG.a" "$NHC98LIBDIR/$MACHINE/Runtime$CFG.a" "$NHC98LIBDIR/$MACHINE/Prelude$CFG.a" "$NHC98LIBDIR/$MACHINE/libdebug$CFG.a" "$NHC98LIBDIR/$MACHINE/Runtime$CFG.a" "$NHC98LIBDIR/$MACHINE/Prelude$CFG.a" "$NHC98LIBDIR/$MACHINE/Runtime$CFG.a

Try adding another
    " "$NHC98LIBDIR/$MACHINE/Prelude$CFG.a
to the end of this line, and maybe another
    " "$NHC98LIBDIR/$MACHINE/Runtime$CFG.a
also.  Afterwards, you must run ./configure again to re-generate the
actual runnable script/nhc98.
