159 # Note that Makefile.SH employs a bare yacc command to generate
160 # perly.[hc] and a2p.[hc], hence you may wish to:
162 # alias yacc='myyacc'

165 # following warnings try invoking Configure like so:
167 # sh Configure -Dbyacc=yacc

173 : we should be OK - perhaps do a test -r?
177 Warning. You do not have a copy of yyparse.c, the default
178 yacc parser template file, in place in /etc.
180 if test -e /samples/yyparse.c ; then
183 There does appear to be a template file in /samples though.
186 cp /samples/yyparse.c /etc
188 before attempting to Configure the build of $package.
194 There does not appear to be one in /samples either.
195 If you feel you can make use of an alternate yacc-like
196 parser generator then please read the comments in the
197 hints/os390.sh file carefully.
