+# The -fno-optimize-sibling-calls should be removed as soon as a bug
+# in GCC concerning the "large" memory model and tail call optimization
+# is fixed.

+# When GCC generates a code for tail call, instead of generating ..

+#   jmp *fnc
+#
+# it generates an assembly code with an illegal immediate prefix:
