* eval.c (rb_eval): added NODE_DSYM, symbol literal with

  interpolation.

* node.h: ditto.

* intern.h: prototypes; rb_is_junk_id, rb_str_dump, rb_str_intern

* object.c (sym_inspect): escape and quote for non-alphanumeric
  symbols.

* parse.y (dsym, tokadd_string, yylex): extended symbol literals.

* parse.y (rb_is_junk_id): added.

* string.c (rb_str_dump, rb_str_intern) : make extern.

* lib/mkmf.rb (create_makefile): deffile should be removed by
  distclean, not clean.
