[Bug libc/4061] New: strtod converts hex floating point to incorrect value

["deianstefan at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

strtod convers 0x100p-7 to an incorrect value -- the value should be 2 but it returns 0.03125. This 
was tested on a GNU/Linux Gentoo Box, kernel version 2.6.17.6, gcc version 4.1.1 and libc version 2.4. 
The following code reproductes the results:

#include <stdio.h>
#include <stdlib.h>
#include <gnu/libc-version.h>

main() {
        long double a=strtod("0x100p-7",0);
        printf("0x100p-7 is 2, not %Lg\n",a);
        printf("libc version: %s\n",gnu_get_libc_version ());
}

output:  
0x100p-7 is 2, not 0.03125
libc version: 2.4
