* utils.c, defs.h (error_begin): New function.

Browse source 
(quit): Print annotation before printing the error message.
	* main.c (return_to_top_level): Print annotation before doing the
	longjmp.
	* symtab.c (decode_line_1): Call error not warning and then
	return_to_top_level.  Call error_begin and printf_unfiltered
	rather calling warning (before calls to return_to_top_level).
	* core.c (memory_error): Use error_begin, printf_unfiltered,
	print_address_numeric and return_to_top_level instead of error.
	Cleans up a FIXME-32x64.
	* language.c (type_error, range_error): Call error_begin
	not just target_terminal_ours.

* utils.c, defs.h (error_begin): New function.
(quit): Print annotation before printing the error message.
* main.c (return_to_top_level): Print annotation before doing the
longjmp.
* symtab.c (decode_line_1): Call error not warning and then

* core.c (memory_error): Use error_begin, printf_unfiltered,
print_address_numeric and return_to_top_level instead of error.
Cleans up a FIXME-32x64.
* language.c (type_error, range_error): Call error_begin
not just target_terminal_ours.
* dbxread.c (stabsect_build_psymtabs): Assign to sym_stab_info
directly, rather than via DBX_SYMFILE_INFO. A cast on the left
side of an assignment is non-portable.
* symtab.c (decode_line_1): Call error not warning and then
return_to_top_level.
* utils.c (query): Change syntax of query annotations to be
consistent with other input annotations.
(prompt_for_continue): Likewise for prompt-for-continue annotation.
