# Note that Makefile.SH employs a bare yacc to generate 
# perly.[hc] and a2p.[hc], hence you may wish to:
#
#    alias yacc='myyacc'
#
# Then if you would like to use myyacc and skip past the
# following warnings try invoking Configure like so: 
#
#    sh Configure -Dbyacc=yacc
#
# This trick ought to work even if your yacc is byacc.
#
if test "X$byacc" = "Xbyacc" ; then
    if test -e /etc/yyparse.c ; then
        : we should be OK - perhaps do a test -r?

Warning.  You do not have a copy of yyparse.c, the default 
yacc parser template file, in place in /etc.
EOWARN
        if test -e /samples/yyparse.c ; then
            cat <<EOWARN >&4

There does appear to be a template file in /samples though.
Please run:

      cp /samples/yyparse.c /etc

before attempting to Configure the build of $package.

EOWARN
        else
            cat <<EOWARN >&4

There does not appear to be one in /samples either.  
If you feel you can make use of an alternate yacc-like 
parser generator then please read the comments in the
hints/os390.sh file carefully.
