It allows defining global variables used in expect functions.

For example, in an .expect.rc file you can have

    set keep --keep_output

and then in procedure dg-runtest in dg.exp have something like:

    global keep
    if ![ info exists keep ] {
      set keep ""
    }
    ...
    dg-test $keep $testcase $flags ${default-extra-flags}
