System: NetBSD nutcracker.stacken.kth.se 2.0E NetBSD 2.0E (NUTCRACKER) #86: Tue May 25 00:18:22 CEST 2004 lha@nutcracker.stacken.kth.se:/usr/src/sys/arch/i386/compile/NUTCRACKER i386
Architecture: i386

>Description:

	struct __res_state is diffrent in libc and on the outside
	libc, this breaks everything that tries to use res_ninit.

>How-To-Repeat:

: lha@nutcracker ; cat foo.c 
#include <sys/types.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <resolv.h>
#include <err.h>

int
main(int argc, char **argv)
{
        int foo[] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }, i;
        struct __res_state stat;
        int bar[] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 };

        res_ninit(&stat);
        for (i = 0; i < sizeof(foo)/sizeof(foo[0]); i++) {
                if (bar[i] != i)
                        errx(1, "bar[i] != i, %d", i);
                if (foo[i] != i)
                        errx(1, "foo[i] != i, %d", i);
        }
        return 0;
}
: lha@nutcracker ; gcc -o foo foo.c
: lha@nutcracker ; ./foo
foo: foo[i] != i, 5


>Fix:
	remove _LIBC from resolv.h ?
