 The 'cstdlib' should have in its beginning:

--------------- clip -----------------------
#ifndef _CPP_CSTDLIB
#define _CPP_CSTDLIB 1

#pragma GCC system_header

#include <bits/c++config.h>
#include <cstddef>

#include <stdlib.h>
--------------- clip -----------------------

and the 'stdlib.h' in the newlib-headers declares
the 'div_t' and 'ldiv_t' :

--------------- clip -----------------------
typedef struct 
{
  int quot; /* quotient */
  int rem; /* remainder */
} div_t;

typedef struct 
{
  long quot; /* quotient */
  long rem; /* remainder */
} ldiv_t;
--------------- clip -----------------------

 Please check which 'stdlib.h' your 'cstdlib' now
includes. There should be nothing with this name
in your build GCC directories, the one in the
possible 'newlib/libc/include'-subdir should though
be the same right one you got into your
$prefix/$target/include during the newlib-installation.

 Any possible 'fixed' <stdlib.h> should not exist
in the '$build/gcc/include', ie. in your :

  /home/alberico/shtools/build-gcc/gcc/include

 If there is, you used some 'forbidden' option like
'--with-headers=' in order to get the newlib headers
'fixed' for GCC, although they should not be fixed.
Anyway the commands:

  $ cd /home/alberico/shtools/build-gcc
  $ find . -name stdlib.h

should easily show where you have any possible faulty
'stdlib.h' now...

Cheers, Kai
