Subject: [RFC 3/3] Cell SPU offloaded stdio: Other stdio functions

Attached is a patch to implement stdio functions w/o FILE operations.

2007-01-09  Kazunori Asayama <asayama@sm.sony.co.jp>

	* libc/machine/spu/Makefile.am: Add objects.
	* libc/machine/spu/Makefile.in: Regenerated.
	* libc/machine/spu/vsscanf.c: New file. Add a stdio function
	implementation.
	* libc/machine/spu/snprintf.c: Ditto.
	* libc/machine/spu/sprintf.c: Ditto.
	* libc/machine/spu/sscanf.c: Ditto.
	* libc/machine/spu/remove.c: Ditto.
	* libc/machine/spu/rename.c: Ditto.
	* libc/machine/spu/tmpnam.c: Ditto.
	* libc/machine/spu/vsnprintf.c: Add initialization routine of
	stdio stuffs.
	* libc/machine/spu/vsprintf.c: Ditto.
