  Log:
    * process.c, include/ruby/intern.h (rb_run_exec_options): externed.
    
    * process.c (save_redirect_fd, save_env_i, save_env, run_exec_dup2,
      run_exec_open, run_exec_pgroup, run_exec_rlimit, rb_run_exec_options):
      save parent's process environments.
      !!!remark!!! these are not thread-safe.
    
    * process.c (rb_spawn_internal): remove calling run_exec_options()
      because cannot restore after spawn. we'll fix this later.
    
    * io.c (pipe_open): ditto.
    
    * test/ruby/test_process.rb (test_execopts_env): upcase environment
      variable name for case insensitive platforms.
    
    * win32/win32.c (init_env): set USER environment variable only when
      USERNAME is available.
