Hi Bruce,

The common way to get rid of these warnings is to insert an invocation of
gl_USE_SYSTEM_EXTENSIONS at the appropriate place in configure.ac.
Could you explicitly define "appropriate place" in the sample above? :)
I took a guess, based upon the configure.ac generated by the original
"gnulib-tool" invocation.
AC_USE_SYSTEM_EXTENSIONS right after AC_INIT can't fail to patch over
the bug, unless AC_REQUIRE ordering is badly botched.
AC_USE_SYSTEM_EXTENSIONS may still have upstream bugs, even in autoconf
2.68. Why do I say this? Because my pending patch [1] to fix some
brokenness in AC_BEFORE makes the autoconf testsuite fail its
AC_USE_SYSTEM_EXTENSIONS test. I still need to investigate why, and
whether the gnulib variant gl_USE_SYSTEM_EXTENSIONS is likewise affected.
