------- Comment #2 from hutchinsonandy at gcc dot gnu dot org 2009-11-20 02:07 ------- I found c99 limit now which explains it.
I was tempted to make PTRDIFF_TYPE signed 32 bits to solve c99 compliance - however that completely useless as we cannot declare array exceeding > 32767 bytes anyway (http://gcc.gnu.org/ml/gcc-patches/2009-11/msg00023.html), despite it being physically possible and with SIZE_TYPE unsigned 16 bits. Skipping the paricular test would seem appropriate - keeping the others which are useful. So should I skip ptrdiff limit test based on pointers being <32 bits? Perhaps ints < 32 bits Or do I use stdint definition of INTPTR_MAX <65535 ? -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=42114
