17 # To get ANSI C, we need to use c89, and ld doesn't exist
20 # To link via definition side decks we need the dll option
21 cccdlflags='-W 0,dll,"langlvl(extended)"'
22 # c89 hides most of the useful header stuff, _ALL_SOURCE turns it on again,
23 # YYDYNAMIC ensures that the OS/390 yacc generated parser is reentrant.
24 # -DEBCDIC should come from Configure.

26 # Turning on optimization breaks perl
35 # On OS/390, libc.a doesn't really hold anything at all,
36 # so running nm on it is pretty useless.
39 # Dynamic loading doesn't work on OS/390 quite yet
43 # Configure can't figure this out for some reason

51 # uname -m output is too specific and not appropriate here
52 # osname should come from Configure

64 # Note that Makefile.SH employs a bare yacc to generate
65 # perly.[hc] and a2p.[hc], hence you may wish to:
69 # Then if you would like to use myyacc and skip past the
70 # following warnings try invoking Configure like so:
72 # sh Configure -Dbyacc=yacc
74 # This trick ought to work even if your yacc is byacc.
76 if test "X$byacc" = "Xbyacc" ; then
77 if test -e /etc/yyparse.c ; then
78 : we should be OK - perhaps do a test -r?
82 Warning. You do not have a copy of yyparse.c, the default
83 yacc parser template file, in place in /etc.
85 if test -e /samples/yyparse.c ; then
88 There does appear to be a template file in /samples though.
91 cp /samples/yyparse.c /etc
93 before attempting to Configure the build of $package.
99 There does not appear to be one in /samples either.
100 If you feel you can make use of an alternate yacc-like
101 parser generator then please read the comments in the
102 hints/os390.sh file carefully.
