+# @$(RUN) ./miniperl make_ext.pl --target=dynamic $@ MAKE=$(MAKE) LIBPERL_A=$(LIBPERL)
+#
+# On Windows or VMS,
+# If '--static' is specified, static extensions will be built.
+# If '--dynamic' is specified, dynamic extensions will be built.
+# If '--nonxs' is specified, nonxs extensions will be built.
+# If '--dynaloader' is specified, DynaLoader will be built.
