* lib/diffseq.h: In commentary, prefer ptrdiff_t to ssize_t.
ptrdiff_t is the natural type for signed indexes.
On a few older platforms, ssize_t is narrower than size_t.

Hi Eric,
We were blindly defining ssize_t to int. On mingw64, this is the
correct size, but the wrong rank, which leads gcc to issue warnings
for %zd printf directives.
* m4/ssize_t.m4 (gt_TYPE_SSIZE_T): Match rank of size_t.
This patch will not help to fix Daniel Berrange's problem

Then how do I explain the compiler
warning that Daniel was seeing under mingw64?
They come from disagreements regarding the integer conversion rank of
'size_t' and 'ssize_t' between GCC and sys/types.h.
When you write printf(%zd,arg) then GCC compares its own built

Test program:

On MSVC 9, ssize_t is not defined, leading to test compilation failures
in test-stdio.c:36, test-sys_uio.c:25, test-unistd.c:40.
According to POSIX:2008, ssize_t ought to be defined in each of
stdio.h
sys/socket.h
sys/types.h
sys/uio.h
unistd.h
This fixes it.

Looks OK to me.
I'm not sure what the License field for ssize_t.m4 should be. The M4

Hello,
this mail is a lengthy story to the most abstract solution and back
to the basic one. Sorry, I couldn't have helped.
The problem, of course, is that the installed header file cannot
assume a config.h and the HAVE_* stuff.
Indeed, this is the root of the problem.
