Backporting within gnulib-common.m4 itself won't work - we have to redefine AC_DEFUN_ONCE before any other gnulib .m4 file that uses it to define another macro. Fortunately, Automake collects all m4/*.m4 files in alphabetical order, so it should be as simple as making a file named 000-gnulib.m4 (or some-such) which is then guaranteed to be included before any other gnulib m4 file. Any thoughts on how best to name/include such a file reliably? I've got the autoconf side running in my sandbox, and am now working on the gnulib side. - -- Don't work too hard, make some time for fun as well!
