New description:

 newlib-1.15.0's inttypes.h's implementation of the
 PRI*PTR macros is broken.

 The %*l macro being chosen doesn't correspond to the type being used as
 intptr_t.

 To reproduce, compile this:
 > cat tmp.c
 #include <stdio.h>
 #include <inttypes.h>

 int main()
 {
   void *null = 0;
   printf( "%" PRIxPTR "\n", (intptr_t) null );
   return 0;
 }


 # for c in /opt/rtems-4.8/bin/*-rtems4.8-gcc; do \
 echo "$c:"; $c -o tmp.o -Wall -c tmp.c; done

 /opt/rtems-4.8/bin/arm-rtems4.8-gcc:
 tmp.c: In function 'main':
 tmp.c:7: warning: format '%llx' expects type 'long long unsigned int', but
 argument 2 has type 'long int'

 /opt/rtems-4.8/bin/avr-rtems4.8-gcc:
 tmp.c: In function 'main':
 tmp.c:7: warning: format '%llx' expects type 'long long unsigned int', but

 /opt/rtems-4.8/bin/bfin-rtems4.8-gcc:
 tmp.c: In function 'main':

 tmp.c: In function 'main':
 tmp.c:7: warning: format '%llx' expects type 'long long unsigned int', but
 argument 2 has type 'int'

 /opt/rtems-4.8/bin/i386-rtems4.8-gcc:
 tmp.c: In function 'main':

 tmp.c:7: warning: long long unsigned int format, different type arg (arg
 2)


 Affected are all targets on all rtems branches.
