Better solution would be to make 5005threaded perl use
the same system as ithreads do
p4raw-id: //depot/perl@11718
#endif
/* Use the reentrant APIs like localtime_r and getpwent_r */
-#if (defined(USE_THREADS) || defined(USE_ITHREADS)) && !defined(USE_REENTRANT_API)
+#if defined(USE_ITHREADS) && !defined(USE_REENTRANT_API)
# define USE_REENTRANT_API
#endif
