New submission from Tim Peters:
1>..\Modules\_pickle.c(710): warning C4293: '>>' : shift count negative or too
big, undefined behavior
1>..\Modules\_pickle.c(711): warning C4293: '>>' : shift count negative or too
big, undefined behavior
1>..\Modules\_pickle.c(712): warning C4293: '>>' : shift count negative or too
big, undefined behavior
1>..\Modules\_pickle.c(713): warning C4293: '>>' : shift count negative or too
big, undefined behavior
1>..\Modules\_pickle.c(1158): warning C4018: '<' : signed/unsigned mismatch
The first 4 should be easy to fix by using a SIZEOF_SIZE_T >= 8 #ifdef test.
The last is on:
if (frame_len < n) { ... raise an exception ...
where `frame_len` is size_t and `n` is Py_ssize_t.
