  17 # Removing subdir objects does not cause too much 'rm' invocations.
  18 # Also, if we rename a source file in a subdirectory, the stale
  19 # compiled object corresponding to the old name still gets removed
  20 # by "make mostlyclean".  See automake bug#10697.
  21 # This is the libtool case.  Keep this test in sync with sister test
  22 # 'subobj-clean-pr10697.sh', which deals with the non-libtool case.
