+#if defined(__MVS__) && !defined(PATH_MAX)
+#define PATH_MAX _XOPEN_PATH_MAX
I've been told that `PATH_MAX` is indeed limited to `_XOPEN_PATH_MAX` and that seems to be the case (based on experimentation) with `realpath`, but I have not seen documentation that supports such an assertion. The scope of this macro definition may be too broad as a solution of dealing with `realpath`.
