AC_INIT(aclocal.m4)

dnl This is required to get past a stupid configure bug when making the rpm.
dnl Basically it is broken to specify the host as a command line argument to
dnl configure on its own, i.e. without giving --host=. It is supposed to work
dnl but doesn't. So this sets host and erases nonopt effectively moving the
dnl standalone command line option into the --host= form.
if test "x$nonopt" != "xNONE"; then
  host="$nonopt"
