[Bug libc/5774] New: some strtod() cases are wrong

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'.
