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
argument 2 has type 'int'
/opt/rtems-4.8/bin/bfin-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/h8300-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 'int'
/opt/rtems-4.8/bin/i386-rtems4.8-gcc:
tmp.c: In function 'main':
tmp.c:7: warning: format '%llx' expects type 'long long unsigned int', but

tmp.c:7: warning: long long unsigned int format, different type arg (arg
2)
Affected are all targets on all rtems branches.
