>Environment:
	
	
System: NetBSD garlique.algebras.org 4.99.2 NetBSD 4.99.2 (GGM_ACPI) #1: Fri Sep 22 14:48:18 EST 2006 ggm@garlique.algebras.org:/data/Build/obj/usr/src/sys/arch/i386/compile/GGM_ACPI i386
Architecture: i386
Machine: i386
>Description:
	I was running build.sh as:

(cd /usr/src; nice ./build.sh -x -u -U -M /data/Build/obj \
	-T /data/Build/tools distribution sets \
		kernel=GGM_ACPI releasekernel=GGM_ACPI
with /usr/src mounted RO, expecting all outputs to the /data/Build/obj tree.

However, during the build of gdb, a yacc pass attempted to write a new .c file
from a .y source, specifying /usr/src as the output path.
>How-To-Repeat:
	run build.sh as above on a clean OBJDIR state from ro /usr/src

	
>Fix:
	I think a Makefile.in or Makefile needs to be BSD-ised to refer
	to the OBJDIR output path in the .c.y rule.
