CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	meyering@sourceware.org	2008-07-25 08:00:20

Modified files:
	.              : configure.in 

Log message:
	Avoid compiler warnings (provoked by new configure.in bug) on RHEL5.
	
	Do not override the default action of AC_CHECK_LIB([readline],...
	(i.e., leave the ACTION-IF-FOUND parameter blank) so that the
	subsequent check for rl_completion_matches can use -lreadline.
	
	Also, replace AC_CHECK_FUNC+AC_DEFINE with an equivalent AC_CHECK_FUNCS call.
