+       * TODO: Added a note about requiring C++ compiler because of a
+         possible problem with libtool autoconf macros.
+       * docs/examples/Makefile.am, proxy/Makefile.am, qemud/Makefile.am,
+         src/Makefile.am, tests/Makefile.am: Pass $(WARN_CFLAGS) when
+         linking, so if -fstack-protector is there, gcc will link to
+         the stack protector library.
+       * tests/xencapstest.c: Allow this test to compile when Xen
+         libraries are not enabled.
+

	* src/test.c, src/libvirt.c, src/virterror.c,
	  include/libvirt/virterror.h: Add a VIR_FROM_TEST error class
	  and ensure that test driver errors are from this class.
	  Tidy up the error messages generated by the test driver when
	  user doesn't add a path to the URL and avoid open ("/").

  to handle CDRom devices with no device name
* tests/sexpr2xmltest.c tests/xml2sexprtest.c
  tests/sexpr2xmldata/sexpr2xml-no-source-cdrom.sexpr
  tests/sexpr2xmldata/sexpr2xml-no-source-cdrom.xml
  tests/xml2sexprdata/xml2sexpr-no-source-cdrom.sexpr
  tests/xml2sexprdata/xml2sexpr-no-source-cdrom.xml: added regression
  tests for this case based on Nobuhiro Itou test inputs.

  warnings when compiling without Xen
Daniel

  src/Makefile.am src/libvirt.c src/qemu_internal.c src/test.c
  src/xen_internal.c src/xen_internal.h src/xend_internal.c
  src/xm_internal.c src/xml.c src/xs_internal.c
  tests/Makefile.am tests/sexpr2xmltest.c tests/xmconfigtest.c:
  allow selective compilation of Xen,QEmu/KVM and test support
  in or out at configure time. Also allows to compile on a system
  without Xen development installed. All drivers are selected by
  default.

        * acinclude.m4: add LIBVIRT_COMPILE_WARNINGS, copied from
        GNOME but with a few more flags we'd been using.

        * configure.in: use that instead of setting CFLAGS
        directly.

        * proxy/Makefile.am, python/Makefile.am, qemud/Makefile.am,
          src/Makefile.am, tests/Makefile.am: use $(WARN_CFLAGS)

        * src/xend_internal.c, src/xm_internal.c: pass the
        connection to virDomainParseXMLDesc()

        * src/xml.[ch]: make virDomainParseXMLDesc accept
        a virConnectPtr so that we can use it later to
        lookup the bridge associated with a network

        * tests/xml2sexprtest.c: just pass NULL here, it's
        safe

  to the XML description and handle its serialization back and
  forth between XML and S-Expr
* tests/sexpr2xmltest.c tests/xml2sexprtest.c
  tests/sexpr2xmldata/sexpr2xml-curmem.*
  tests/xml2sexprdata/xml2sexpr-curmem.*: added specific regression
  tests for this, this didn't disturb any of the other tests.
