[Bug libc/3855] New: strtod("0x.") consumes too many characters

[jsm28 at gcc dot gnu dot org]

As an argument to strtod, "0x." has "0" as the longest valid numeric prefix. 
strtod (current CVS) wrongly treats the whole string as valid.  Testcase:

#include <stdlib.h>
int
main(void)
{
  const char *s = "0x.";
  char *ep;
  double r = strtod(s, &ep);
  if (r != 0)
    abort();
  if (ep != s + 1)
    abort();
  exit(0);
}
