System: NetBSD 5.99.30 NetBSD 5.99.30 (DARLING) #0: Thu 
Jun 10 20:15:59 CEST 2010 
Architecture: i386
Machine: i386
For a memory-challenged old system I keep around, I normally build a
custom kernel with all of the non-needed stuff removed.  Thus the
config file has no references to PCI or USB or other modern devices.
Unfortunately the custom kernel would not build this time around.  I
had to apply the attached patches.
o The prototype for config_rootfound is declared in sys/device.h.  Without
  including this file the compiler complains about "implicit declaration"
  of said function.  Patch 1 explicitly includes sys/device.h in
  i386/i386/autoconf.c instead of hoping that some other header file
  will include it for us.
o The vga_posth variable is only used/referenced inside a #if NPCI>0/#endif
  block.  Arrange for the variable declaration to be enclosed similarly.
