+Fix for SAPPHIRE-12162/SAPPHIRE-12122: fix unstable PR_LocalTimeParameters by
+#define-ing HAVE_POINTER_LOCALTIME_R and HAVE_LOCALTIME_R. These #define's
+cause the compiler to use the threadsafe localtime_r function instead of
+localtime when determining PR_LocalTimeParameters, which avoids changes in
+PR_LocalTimeParameters at inopportune times (such as computing
+GetNextWeeklyOccurrence).
+
+In addition, PR_LocalTimeParameters will always call tzset() when populating
+offsets to guarantee that the most current timezone information will be used.
