Interesting.  My flex(1) doesn't have a "-l" option.  It shouldn't
hurt.

You needed to REPLACE THE ENTIRE RULE for the "ncgentab.c" and
"ncgentab.h" targets, i.e., change

        ncgentab.c \
        ncgentab.h:     ncgen.y ncgenyy.c ncgen.h
                @case `uname` in \
                OSF1) \
                    echo 1>&2 "(expect 1 shift/reduce conflict)"; \
                    set -x; \
                    bison -y -d ncgen.y; \
                    cat y.tab.c >ncgentab.c && rm y.tab.c; \
                    cat y.tab.h >ncgentab.h && rm y.tab.h; \
                    set +x; \
                    ;; \
                *)  echo 1>&2 "Warning: $@ is out-of-date with respect to 
ncgen.y"; \
                    echo 1>&2 "Warning: It should be recreated via $(yacc)" \
                        "on an OSF/1 system"; \
                    : set -x; \
                    :  bison -y -d ncgen.y; \
                    : mv y.tab.c ncgentab.c; \
                    : mv y.tab.h ncgentab.h; \
                  : set +x; \
                    ;; \
                esac

to

        ncgentab.c \
        ncgentab.h:     ncgen.y ncgenyy.c ncgen.h
                bison -y -d ncgen.y
                mv y.tab.c ncgentab.c
                mv y.tab.h ncgentab.h

Replace the rule, remove the files "ncgentab.c" and "ncgentab.h", and
try again.
