doc: mention glibc, OS X, Cygwin [S]SIZE_MAX buglet

More platforms have similar bugs, and in the case of glibc on s390,
the bug is in SIZE_MAX instead of SSIZE_MAX.

* doc/posix-headers/stdint.texi (stdint.h): Document the bugs.
* doc/posix-headers/limits.texi (limits.h): Document the bugs.

 Some C preprocessors mishandle constants that do not fit in @code{long int}.
 For example, as of 2007, Sun C mishandles @code{#if LLONG_MIN < 0} on
 a platform with 32-bit @code{long int} and 64-bit @code{long long int}.
