This is the bug number 3190:
http://gcc.gnu.org/cgi-bin/gnatsweb.pl?database=gcc&pr=3190

You probably clicked on "send email to interested parties" in gnatsweb, 
but your message didn't appear there because you removed the bug number 
from the subject.  Just a guess, I'm not an expert in gnatsweb.

That's what I do in GNU Midnight Commander.

    char s[1024];
    /* fool gcc to prevent a Y2K warning */
    char time_format[] = "_c";
    time_format[0] = '%';
    time (&t);
    strftime (s, sizeof (s), time_format, localtime (&t));

This code implements a command "insert date/time" in the internal editor.  
And if I use "%c", the error is the same:

warning: `%c' yields only last 2 digits of year in some locales

I agree.  I'm printing the date for the user in the format preferred by
the user.  That's the expected behavior.  If the user wants only two last
2 digits of year, it's not my problem - it's a problem of that locale.
