That tells me that you are trying to compile the current ROTD
with an installed compiler that dates from before an incompatible
change to the Mercury standard library. If you install the ROTD
from the source distribution, setting your path to *not* include
any Mercury compilers when you invoke the configure script,
this problem should not occur.

I will update the configure script to detect this problem.
