Thanks for checking this.  Please bear with me, as I can't easily
test this directly.  How about the following further patch, which
I just now installed?

2006-07-20  Paul Eggert  <address@hidden>

        * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
        compiler complains about it, even if things works after the
        complaint.  Problem reported by Peter O'Gorman.
