CVSROOT:	/cvs/cluster
Module name:	cluster
Changes by:	fabbione at sourceware.org	2007-09-19 11:07:22

Modified files:
	.              : configure 
	csnap-kernel/src: Makefile 
	gfs-kernel/src/gfs: Makefile 
	gnbd-kernel/src: Makefile 
	make           : defines.mk.input 

Log message:
	Fix configure and Makefiles to cope with kernel built with O=/path...
	
	Original patch by Joel Becker (joel.becker at oracle.com)
	
	NOTE for developers: you will need to re-run ./configure to update make/defines.mk
	NOTE for packages: you might need to change the way ./configure is invoked to cope
	with kernel_build vs kernel_src
