+       Map compile-time constant references for POSIX clocks.
+
+       * include/time.h (CLOCK_REALTIME, CLOCK_MONOTONIC): Redefine, using...
+       (__MINGW_POSIX_CLOCKAPI): ...this new macro; it converts clock indices
+       to odd-valued compile-time constant pseudo-pointers, (distinguishable
+       from real pointers which are always even-valued), which may be passed
+       as clockid_t references in POSIX clock API function calls.
+
+       * mingwex/clockapi.h (struct __clockid__): Specify 4-byte alignment.
+       (__clock_api_is_valid): Change return type to "clockid_t".
+
+       * mingwex/clockapi.c (__clock_api_is_valid): Return an even-valued,
+       non-NULL, "clockid_t" reference pointer, or "NULL" if invalid; use...
+       (clock_reference): ...this new static inline function, to convert...
+       (CLOCK_REALTIME, CLOCK_MONOTONIC): ...these odd-valued pseudo-pointers
+       to their actual run-time pointer equivalents; delete their physical
+       initializations, which have now become invalid.
+
+       * mingwex/clockres.c (clock_getres)
+       * mingwex/clocktime.c (clock_gettime)
+       * mingwex/clockset.c (clock_settime): Update the "clockid_t" argument
+       to match the real pointer returned by __clock_api_is_valid()
