We are expecting to find 'stdint.h' because we are looking for the
"intptr_t" type.

Do you know where it is supposed to be found on Sun OS?

At the moment we have this code block:

#ifndef _DIRSTATE_HELPERS_C_H
#define _DIRSTATE_HELPERS_C_H

/* for intptr_t */
#ifdef _MSC_VER
#include <io.h>
#else
#include <stdint.h>
#endif

#endif

We can certainly extend that for Sun, even if it is only "ifdef SUN:
typedef int intptr_t
"

We use that as part of this code:

cdef int _is_aligned(void *ptr):
    """Is this pointer aligned to an integer size offset?

    :return: 1 if this pointer is aligned, 0 otherwise.
    """
    return ((<intptr_t>ptr) & ((sizeof(int))-1)) == 0

I believe "intptr_t" is an integer large enough to hold a pointer, and
is necessary because some things really don't like it when you do
integer math on a "void *".
