18 # To get ANSI C, we need to use c89, and ld doesn't exist
19 # You can override this with Configure -Dcc=gcc -Dld=ld.
27 # -DMAXSIG=38 maximum signal number
28 # -DPERL_IGNORE_FPUSIG=SIGFPE allows Perl to be cavalier with FP overflow
29 # (particularly in numeric.c:S_mulexp10())
30 # -DOEMVS is used in place of #ifdef __MVS__ in certain places.
31 # -D_OE_SOCKETS alters system headers.
32 # -D_XOPEN_SOURCE_EXTENDEDA alters system headers.
33 # c89 hides most of the useful header stuff, _ALL_SOURCE turns it on again.
34 # YYDYNAMIC ensures that the OS/390 yacc generated parser is reentrant.
35 # -DEBCDIC should come from Configure and need not be mentioned here.

165 # alias yacc='myyacc'
167 # Then if you would like to use myyacc and skip past the
168 # following warnings try invoking Configure like so:
170 # sh Configure -Dbyacc=yacc
172 # This trick ought to work even if your yacc is byacc.

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