+# This disables the long/short jump optimization.
+# I use sysV68 R3V7.1 RM04 (phdm@info.ucl.ac.be)
+# Since ss-950318, with jump optimization enabled, "as" issues a warning
+# when assembling combine.s :
+#   aline nnnnn : Warning: Table overflow: some optimizations lost (SDIs)
+# but later "ld" complains with
+#   ld: relocation entry found for non-relocatable symbol in combine.o
+# and the produced "cc1" fails with SIGSEGV
+# Another possible fix would be to split combine.c.
