  dnl A replacement for autoconf's macro by the same name.  This version
  dnl uses `ac_lib' rather than `i' for the loop variable, but more importantly
  dnl moves the ACTION-IF-FOUND ([$]3) into the inner `if'-block so that it is
  dnl run only if one of the listed libraries ends up being used (and not in
  dnl the `none required' case.
  dnl I hope it's only temporary while we wait for that version to be fixed.
