What is the purpose of __need_inttypes?

[Sebastian Huber <sebastian dot huber at embedded-brains dot de>]

Hello,

what is the purpose of __need_inttypes? It is only defined by 
"newlib/libc/machine/powerpc/machine/stdlib.h".

            * libc/include/sys/types.h: Support __need_inttypes macro
            that only sets the __intxx and __uintxx types.
            * libc/machine/powerpc/Makefile.am: Add stdlib to include 
directories
            to get mprec.h.
            * libc/machine/powerpc/Makefile.in: Regenerated.
            * libc/machine/powerpc/vfprintf.c: Fix state variable type.
            * libc/machine/powerpc/vfscanf.c: Fix state variable type.  
Remove
            redundant fixed-point conversion prototypes.
            * libc/machine/powerpc/machine/stdlib.h[__SPE__]: Include 
<sys/types.h>
            after setting __need_inttypes.

suggests that we should be able to get rid of __need_inttypes and simply 
include <machine/_default_types.h>? However, no __intxx and __uintxx 
types are used in this file.
