(init_cmd_lists): Initialize endianlist.
(init_main): Add commands ``set endian big'', ``set endian

BITS_BIG_ENDIAN to switch at run time rather than at compile time.

number.

building up lists as return values.

anymore).

notification protocol.
* (gdbtk_tcl_busy gdbtk_tcl_idle): Straighten out buttons, remove
catches.
* (interactive_cmd): Use this wrapper around button invocations
of many commands. This will catch errors and put the results into
the command window. It also updates all the other windows.
* Also, change reliefs of most things to sunken. This actually
looks better.
* (create_file_win): Fix margin binding to allow breakpoints to
work again.

should be RETURN_MASK_ERROR, unless for some reason it is more

useful to abort only the portion of the operation inside the
