- * This define and the code below is to trigger thread-safe behavior
- * in dtoa.cc, per this comment from the file:
- *
- * #define MULTIPLE_THREADS if the system offers preemptively scheduled
- *	multiple threads.  In this case, you must provide (or suitably
- *	#define) two locks, acquired by ACQUIRE_DTOA_LOCK(n) and freed
- *	by FREE_DTOA_LOCK(n) for n = 0 or 1.  (The second lock, accessed
- *	in pow5mult, ensures lazy evaluation of only one copy of high
- *	powers of 5; omitting this lock would introduce a small
- *	probability of wasting memory, but would otherwise be harmless.)
- *	You must also invoke freedtoa(s) to free the value s returned by
- *	dtoa.  You may do so whether or not MULTIPLE_THREADS is #defined.
