C99 requires SIZE_MAX to be declared with the same type as the integral promotion of size_t, but OSX mistakenly defines it as an 'unsigned long long' expression even though size_t is only 'unsigned long'. Rather than futzing around with whether size_t is 32- or 64-bits wide (which would be needed if we cared about using SIZE_T in a #if expression), just hard-code it with a cast. This is not a strict C99-compliant definition, because it doesn't work in the preprocessor, but if we later need that, the build will break on Mac to inform us to improve our replacement at that time. See also https://patchwork.ozlabs.org/patch/542327/ for an instance where the wrong type trips us up if we don't fix it for good in osdep.h. Some versions of glibc make a similar mistake with SSIZE_MAX; the goal is that the approach of this patch could be copied to work around that problem if it ever becomes important to us.
