>Description:
	The strptime(3) function succeeds with input that it should fail on according to the given format string.
	Excerpt from the strptime(3) manpage:
	   It returns NULL if one of the conversions failed.
>How-To-Repeat:
	Compile and run this test program. strptime() should obviously fail on input 'March' cause format '%d'
	is not satisfied.
	
#include <stdio.h>
#include <time.h>

int main(int argc, char *argv[])
{
        struct tm tm;
        char *date="March";
        char *test=strptime(date, "%B %d", &tm);
                        
        if(test)
                printf("Broken\n");
        else
                printf("OK\n");

        return 0;
}
