Test gcc.dg/c99-stdint-1.c checks for range of__PTRDIFF_TYPE__ and fails for
avr target.
test_misc_limits (void)
{
CHECK_SIGNED_LIMITS_2(__PTRDIFF_TYPE__, PTRDIFF_MIN, PTRDIFF_MAX, -65535L,
65535L);
On AVR pointers and integers are 16bit.
INTPTR_MIN =-32768
INTPTR_MAX = 32767
UINTPTR_MAX = 65535U
__PTRDIFF_MAX__ is set by gcc at 32767 and so stdint.h gives PTRDIFF_MAX 32767
and PTRDIFF_MIN -32768
I am not sure why minimum range limits are applied in this test or if
test/gcc/target is wrong.
