	* string.c (_stp_string_init): Deleted.
	(_stp_sprintf): Deleted.
	(_stp_vsprintf): Deleted.
	(_stp_string_cat_cstr): Deleted.
	(_stp_string_cat_string): Deleted.
	(_stp_string_cat_char): Deleted.
	(_stp_string_ptr): Deleted.
	(_stp_string_cat): Deleted.
	(_stp_snprintf): Moved from vsprintf.c.
	(_stp_vscnprintf): Moved from vsprintf.c.

	* string.h (STP_STRING_SIZE): Deleted.
	(STP_NUM_STRINGS): Deleted.
	Remove all references to type "String".

        * vsprintf.c (_stp_vscnprintf): Moved to string.c.
	(_stp_snprintf): Moved to string.c

	* sym.c (_stp_symbol_sprint): Replaced with
	_stp_symbol_print, which writes to the print buffer.
	(_stp_symbol_sprint_basic): Replaced with
	_stp_symbol_snprint.

	* runtime.h: Include io.c.

	* stat-common.c: Use new _stp_print* functions.
	* stat.c: Ditto.

	* regs.c: Renamed to regs-ia64.c.
	* current.c: Renamed regs.c.
	* regs-ia64.c: New file (renamed from regs.c).

	* stack.c (_stp_stack_sprint): Renamed _stp_stack_print
	and now just prints to the print buffer. Calls
	__stp_stack_print instead of __stp_stack_sprint.
	(_stp_stack_snprint): New function. Calls _stp_stack_print and
	then copies the print buffer into a string.
	(_stp_stack_printj): Deleted.
	(_stp_ustack_sprint): Deleted.
	* stack-*.c: Rewritten to print instead of writing to strings.
	Uses new _stp_print* functions.

	* print.c (_stp_printf): Create new function instead of macro.
	(_stp_print): Ditto.
	(_stp_print_char): New function.

	* map.c: Use _stp_print() and _stp_print_char()
	instead of _stp_print_cstr().

	* io.c (_stp_vlog): Use _stp_print() instead
	of _stp_string_cat_cstr().

	* copy.c (_stp_string_from_user): Deleted.
