Observe the following code:

volta$ cat strtod-test.c
#include <stdlib.h>
#include <stdio.h>
int main(int argc, char **argv) {
  double d;
  char *endp;
  char *s = argv[1];
  if (argc != 2)
  {
    printf("Usage: %s string\n", argv[0]);
    return 1;
  }
  d = strtod(s, &endp);
  printf("Got value %g, string tail %s\n", d, endp);
  return 0;
}

volta$ ./strtod-test 'Nan(anana)ana'
Got value nan, string tail )ana

According to ISO C99 7.20.1.3 para 3, the trailing ')' is also part of the 
expected form in the NAN(n-char-seq-opt). Therefore the result should be 'ana'.
