FreeBSD bayonetta.local 9.0-CURRENT FreeBSD 9.0-CURRENT #0 r218938M: Mon Feb 21 23:10:51 PST 2011     gcooper at bayonetta.local:/usr/obj/usr/src/sys/BAYONETTA  amd64
>Description:
Since mdf's rototilling of SYSCTL(9) in r217586, emulators/*qemu* is failing to build with errors like this:

/usr/ports/emulators/qemu-devel/work/qemu-0.13.0/bsd-user/syscall.c: In function 'sysctl_oldcvt':
/usr/ports/emulators/qemu-devel/work/qemu-0.13.0/bsd-user/syscall.c:215: error: 'CTLTYPE_QUAD' undeclared (first use in this function)
/usr/ports/emulators/qemu-devel/work/qemu-0.13.0/bsd-user/syscall.c:215: error: (Each undeclared identifier is reported only once
/usr/ports/emulators/qemu-devel/work/qemu-0.13.0/bsd-user/syscall.c:215: error: for each function it appears in.)

What needs to happen is that the instance of CTLTYPE_QUAD needs to be replaced with CTLTYPE_U64:

$ grep -B 4 -A 4 _QUAD /usr/ports/emulators/qemu-devel/work/qemu-0.13.0/bsd-user/syscall.c 
    case CTLTYPE_ULONG:
        *(uint64_t *)holdp = tswap64(*(unsigned long *)holdp);
        break;
#endif
    case CTLTYPE_QUAD:
        *(uint64_t *)holdp = tswap64(*(uint64_t *)holdp);
        break;
    case CTLTYPE_STRING:
        break;
>How-To-Repeat:
Upgrade to CURRENT r217586+ and try to build emulators/*qemu*.
>Fix:
Patch with an ifdef, like:

#if __FreeBSD_version__ < 900031
    case CTLTYPE_QUAD:
#else
    case CTLTYPE_U64:
#endif

Unfortunately mdf@ didn't bump __FreeBSD_version__ appropriately for the SYSCTL(9) KPI change.
