System: NetBSD blubb.pdc.kth.se 1.6T NetBSD 1.6T (BLUBB) #531: Thu May 29 13:09:25 CEST 2003 joda@blubb.pdc.kth.se:/usr/misc/src/netbsd/netbsd-cvs/src/sys/arch/i386/compile/BLUBB i386

>Description:

Currently printf("%#.o", 0) produces the empty string (""), and this
is correct in terms of C89, but C99 includes this piece of text: "if
the value and precision are both 0, a single 0 is printed". This
indicates that the output should be "0".

But I'm not sure I think this makes much sense. For instance "%#.x"
would still result in "".


So either we should fix printf to comply with C99, or we should decide
that this is just rubbish. I have not seen a rationale for C99, so I
don't know why this change was made.

>How-To-Repeat:
#include <stdio.h>

main()
{
    printf("|%#.o|\n", 0);
}

>Fix:

None supplied.
