The above message contained the following:

Excellent!  Thanks for sending this in.

The "preferred" way to do this would be

    make distclean
    ... LIBS=-lg2c ./configure ...

This is bizarre.

Does the same thing happen if you execute a "make clean" in the
"nf_test" subdirectory first?  For example:

    cd nf_test
    make clean
    ...
    make >make.log 2>&1
    make test >test.log 2>&1
