 /*
  * 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.
