[Bug libc/625] New: lconv::frac_digits != CHAR_MAX in "C" locale


According to 7.11, p2 of C99, the value of lconv::frac_digits is required to be
equal to CHAR_MAX in the "C" locale. GNU glibc on PPC64 sets the value to 127
instead of CHAR_MAX (which is 255 on this platform, since char is unsigned).

$ cat t.c && gcc t.c && ./a.out 
#include <assert.h>
#include <limits.h>
#include <locale.h>

int main ()
{
    struct lconv* lc = localeconv ();

    assert (lc->frac_digits == CHAR_MAX);
}

a.out: t.c:9: main: Assertion `lc->frac_digits == (127 * 2 + 1)' failed.
Aborted

$ ldd a.out 
        libc.so.6 => /lib/tls/libc.so.6 (0x0feb9000)
        /lib/ld.so.1 => /lib/ld.so.1 (0x40000000)
