18 ?S: This variable holds the name of the compiler compiler we
19 ?S: want to use in the Makefile. It can be yacc, byacc, or bison -y.
22 ?S: This variable contains any additional yacc flags desired by the
23 ?S: user. It is up to the Makefile to use this.
25 : determine compiler compiler
34 if $test -f "$byacc"; then
38 if $test -f "$bison"; then
42 $package no longer requires a compiler compiler, so the following is optional.
44 rp="Which compiler compiler ($rp) shall I use?"
53 echo "(Adding -y option to bison to get yacc-compatible behaviour.)"
60 : see if we need extra yacc flags
67 Your yacc program may need extra flags to normally process the parser sources.
68 Do NOT specify any -d or -v flags here, since those are explicitely known
69 by the various Makefiles. However, if your machine has strange/undocumented
70 options (like -Sr# on SCO to specify the maximum number of grammar rules), then
71 please add them here. To use no flags, specify the word "none".
74 rp="Any additional yacc flags?"
