I have been going through the gcc tests for V4.5 and come across some
issues with avr-lic stdint.h
The tests that fails are gcc/gcc/testsuite/gcc.dg/c99-stdint-1.c
gcc will create it's own stdint.h and this is fine for V4.5. I have
attached this for reference.
The definition of UINT8_MAX is unsigned e.g. 255U - this fails test.
255 is ok
wchar limits are not defined- ok we dont have wchar.h but we should
still define the types.
There is another issue related to ptrdiff type. This is posted as gcc
bug - since it is possible that this particular subtest is
inappropriate for avr.
