for describing the command and control types.
(struct command_line): Add new fields to keep track of the command
type and body associated with the command.
* top.c: Include value.h. Delete whitespace at the end of lines.
(build_command_line, get_command_line): New functions.
(execute_control_command, while_command, if_command): Likewise.
(realloc_body_list, read_next_line): Likewise.
(recurse_read_control_structure): Likewise.
(execute_user_command): Call execute_control_command.
(read_command_lines): Simplify by calling read_next_line, call
read_control_structure for "if" and "while" commands.
(free_command_lines): Free new fields in the command structure.
(define_command): Reset control_level to zero.
(init_main): Install command handlers for "if" and "while" commands.
--enable-xxx configure option by adding ENABLE_{CLIBS DEPFILES}
where appropriate.
* General hackery to support alternate user-interface.
* breakpoint.c (mention, delete_breakpoint, enable_breakpoint,
disable_breakpoint): Call hooks for alternate user-interface.
* defs.h: Add declarations for alternate user-interface hooks.
* main.c (main): Add --nw (and --nowindows) options to disable
the GUI.
* (near call to command_loop): Call command_loop_hook if set.
* (fputs_unfiltered): Call fputs_unfiltered_hook if set.
* stack.c: Call print_frame_info_listing_hook if set.
* top.c (gdb_init): Initialize targets.c and utils.c prior to
other files to make sure that calls to error and warning will
work. Call init_ui_hook after everything else.
* utils.c (query): Call query_hook if set.
* (gdb_flush): Call flush_hook if set.
* Change _initialize_utils to initialize_utils cuz we don't use
automatic initialization of utils.c anymore.
* Support for TK GUI.
* Makefile.in: Add rule for gdbtk.o.
* configure.in: Add support for --enable-gdbtk.
* gdbtk.c: New file. Contains support routines for TK interface.
* gdbtk.tcl: New file. Implements GUI policy.
* remote.c: Get rid of #ifdef DONT_USE_REMOTE. It's no longer
necessary.
to new file top.c. Make things extern instead of static and
similar rearrangements to deal with this.
* top.h: New file.
* utils.c: Move fputs_unfiltered to main.c. Remove
FPUTS_UNFILTERED_OVERRIDE ifndef.
* Makefile.in: Change so that gdb uses main.c, utils.c, and top.c,
and libgdb uses utils.c and top.c.
