During the configure test, the AM_PATH_XML2 macro compiles a test program
which includes the xml headers and checks that the version number matches
your request.

When invoking C++, the CFLAGS variable is not used and thus the -I directive
is missing. The test is compiled as C++ b/c in the configure.ac is:


=2E.. which is normal for a purely C++ project.
