  New Revision: 62030

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=62030

  Log:
    load.c: use fstring instead of OBJ_FREEZE
    
    These strings already exist (or will exist soon) in the fstring
    table, so avoid the duplicate, sooner.

  Modified files:
    trunk/encoding.c
