  45 **  Global Declarations
  46 **
  47 **      Virtually all non-local variable declarations are made in this
  48 **      file.  Exceptions are those things which are initialized, which
  49 **      are defined in "externs.c", and things which are local to one
  50 **      program file.
  51 **
  52 **      So far as I know, nothing in here must be preinitialized to
  53 **      zero.
  54 **
  55 **      You may have problems from the loader if you move this to a
  56 **      different machine.  These things actually get allocated in each
  57 **      source file, which UNIX allows; however, you may (on other
  58 **      systems) have to change everything in here to be "extern" and
  59 **      actually allocate stuff in "externs.c"
