------- Comment #2 from ccoffing@xxxxxxxxxx  2007-07-06 13:34 -------
Strict aliasing (which defaults to on in gcc 4.2 when using -O2, -O3, or -Os)
is breaking libxenstore.  As posted on xen-devel, a work-around is:

--- xen-3.1-testing.orig/tools/xenstore/Makefile
+++ xen-3.1-testing/tools/xenstore/Makefile
@@ -6,7 +6,7 @@ MAJOR = 3.0
 MINOR = 0

 PROFILE=#-pg
-BASECFLAGS=-Werror
+BASECFLAGS=-Werror -fno-strict-aliasing
 # Make gcc generate dependencies.
 BASECFLAGS += -Wp,-MD,.$(@F).d
 PROG_DEP = .*.d
