Can not build kernel with modular ata and ATA_CAM

[Mitya]

My kernel options:

# Bus support.
device          acpi
device          pci

# Modular ATA
device          atadisk         # ATA disk drives
device          atacore         # Core ATA functionality
device          atapci          # PCI bus support; only generic chipset 
support
device          ataintel        # Intel

options         ATA_CAM         # Handle legacy controllers with CAM
options         ATA_STATIC_ID   # Static device numbering

# ATA/SCSI peripherals
device          scbus           # SCSI bus (required for ATA/SCSI)
device          da              # Direct Access (disks)
device          pass            # Passthrough device (direct ATA/SCSI 
access)

make's output:

*** [kernel] Error code 1

I found differences in ata-all.c and ata-all.h

In ata-all.c:
#ifndef ATA_CAM
void
ata_setmode(device_t dev)
{

But, in ata-all.h:
void ata_setmode(device_t dev);

without any #ifdef or #ifndef
