for procfs support.
* configure.in (alpha-dec-osf*): Use alpha-osf2.mh for OSF/1
release 2.x and higher, else alpha-osf1.mh, as the procfs support
in release 1.x is incomplete.

loader under Alpha OSF/1.

commands.
* top.c (struct user_args): Structure for holding arguments to
user defined commands.
(print_command_line): Delete unused "tmp_chain" variable. Clean
up flow control by having cases exit in the same manner.
Before executing a command or evaluating an expression, substitute
the current $arg0..$arg9 values if the command/expression uses them.
(arg_cleanup): New function.
(setup_user_args, locate_arg, insert_args): Likewise.
(execute_user_command): Allow arguments to user defined commands.
* Allow if/while commands to be used within a breakpoint command
list.
* breakpoint.c (bpstat_do_actions): Call execute_control_command
rather than execute_command (passes entire command structure rather
than just the command line text).
(breakpoint_1): Use "print_command_line" to print a breakpoint
command line (including control structures).
* gdbcmd.h (execute_control_command): Provide extern decl.
(print_command_line): Likewise.
* top.c (execute_control_command): No longer static.

line, including control structures.
Various name changes to match those used by hp-symtab.h.
No longer sanitize away hpread changes. Merge ChangeLog.hpread into
ChangeLog and ChangeLog-93.
* NEWS: Mention filename completion and "info line" enhancements.
* main.c (symbol_completion_function): On "info t foo", return NULL,
don't error().
* main.c (symbol_completion_function): Don't use readline word
breaking. Use new calling convention for c->completer and
complete_on_cmdlist.
* command.h (struct command): Change arguments; now the text passed
to completer does not have any word breaking done. New arg word.
* symtab.{c,h} (make_symbol_completion_list): Do word breaking. Take
word argument.
* {main.c,gdbcmd.h} ({filename,noop}_completer): Take word argument.
* command.{c,h} (complete_on_cmdlist): Take word argument.
* command.c (lookup_cmd_1): Doc fix.
* demangle.c: Change all references to cfront to ARM, since the
actual algorithm is the one specified in the Annotated Reference
Manual. This was confusing users into thinking that full cfront
support was implemented.
* dwarfread.c (CFRONT_PRODUCER): Remove, was never really used.
* eval.c (evaluate_subexp): For STRUCTOP_PTR pass the arg type
directly to lookup_struct_elt_type, which will do the
dereferencing itself.
* gdbtypes.c (lookup_struct_elt_type): Expand comments. Fix
NULL dereferencing bug for unnamed structs, comment out
questionable code.
