[Bug libc/4772] New: strptime() doesn't support strftime()'s flags

["inkerman42 at gmail dot com" <sourceware-bugzilla at sourceware dot org>]

Tomasz KÄ?pczyÅ?ski has found a bug in strptime(): its format specification
doesn't support strftime()'s flags.


Steps to reproduce:

$ cat foo.c
#define _XOPEN_SOURCE

#include <stdio.h>
#include <time.h>

int
main(void)
{
    struct tm tm;

    printf("%s\n", strptime("1", "%-d", &tm) ? "Success!" : "Woe is me!");

    return 0;
}
$ gcc foo.c && ./a.out
Woe is me!
$


As a result, gnucash misparses dates in, at least, Polish and Czech locale (see
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=243513).

The attached patch against cvs head causes strptime() to correctly parse and
interpret (i.e. ignore) flags and field width.
