NumLock_Is_Gold is mostly used in EDT mode. If NumLock_Is_Gold=1,
when pressing NumLock, the keycode will be returned, otherwise
it won't.

The NumLock_Is_Gold can be changed by the user to change the behaviour
of the numeric keypad. EDT mode should require("x-keydefs"), but when
the call is made, NumLock_Is_Gold might be 0 and Key_NumLock will
remain empty (""). Therefore the test for NumLock_Is_Gold does not
belong in x-keydefs.

If EDT emulation would work in xjed, the ifdef IBMPC would prevent it
to work correctly. (EDT mode should be rewritten to use Key_XXX
variables).

Another problem is the IBMPC symbol which is misleading. In fljed it
is defined, but the keyboard keycodes are nothing like the old DOS
keycodes.

I think IBMPC and IBMPC_SYSTEM should be extended by something like:
   * DOS_KEYBOARD
   * DOS_FILESYSTEM
   * others if necessary:
      - CR-LF line terminator
      - support for signals
      - file permissions
      - screen resizing (screen_w132)
      - mouse support
      - ...

wjed defines: IBMPC_SYSTEM, DOS_FILESYSTEM, DOS_KEYBOARD
fljed on windows defines: IBMPC_SYSTEM, DOS_FILESYSTEM
