>Description:
	The build environment is -current as of today or a day or two ago. 
	Essentially, using the kernel config listed below causes it to choke
	because the wdc_isa code depends on functions which are listed in
	sys/dev/ic/wdc.c which itself ends up not being included in the Makefile
	and dependencies. The functions in specific are:

	#      link  BATTLE/netbsd
	ld -T ../../../../arch/i386/conf/kern.ldscript -Ttext c0100000 -e start -X -o netbsd ${SYSTEM_OBJ} ${EXTRA_OBJ} vers.o
	wdc_isa.o(.text+0x119): In function `wdc_isa_probe':
	: undefined reference to `wdc_init_shadow_regs'
	wdc_isa.o(.text+0x155): In function `wdc_isa_probe':
	: undefined reference to `wdcprobe'
	wdc_isa.o(.text+0x336): In function `wdc_isa_attach':
	: undefined reference to `wdc_init_shadow_regs'
	wdc_isa.o(.text+0x34a): In function `wdc_isa_attach':
	: undefined reference to `wdcintr'
	wdc_isa.o(.text+0x376): In function `wdc_isa_attach':
	: undefined reference to `wdcattach'
	*** Error code 1

	It would appear that some recent work done to introduce these shadow
	registers may have inadvertently made them dependent on options
	which are there to support pci machines? Or perhaps I'm missing
	something. It wouldn't be the first time.

>How-To-Repeat:
	. Update to 3.99.15 (most recent I could find) as of.. hrm.. Dec 31 05
	anyway..
	. Rebuild config, and install it.
	. Use the following kernel config:

 You don't have a 'wd* at wdc?' line, that's probably the immediate cause
 of the error.  Nevertheless, it shouldn't happen.  But at least as it
 is, the wdc line is useless.

 That's what I thought too, but I wasn't sure what to do about it. I just 
 added in the line "wd* at wdc?" and it looks like it makes it choke, 
 too, during the config:

 BATTLE:720: `wd' cannot attach to `wdc'
 *** Stop.

 Yes, because there is one more indirection:

 atabus* at wdc?
 wd* at atabus? drive ? flags 0x0000

 This bug seems to still be open, so I'll just give a quick shout, in 
 case you're still having this problem.

 You don't need the:

 wd* at wdc?

 line in order to get it to compile, but you *do* need the:

 atabus* at ata?

 to get it to compile.  It took me a few minutes of experimentation with 
 the GENERIC conf file to figure this out.

 Hope this helps.

 Peace...  Sridhar

this is a 2006 bug report about a build issue. it's highly unlikely that it contains information that can applied to -current.
