dnl This is not pretty. I've just taken the autoconf code and wrapped
-dnl it in an AC_DEFUN.
-dnl
-dnl CAUTION: This is very fragile. It relies on several checks that
-dnl are still in fileutils' configure.in:
-dnl FIXME: add AC_REQUIRE uses to pull in all definitions required
-dnl for all uses of $ac_cv_func_* and $ac_cv_header_* variables below.
+dnl it in an AC_DEFUN and made some other fixes.
