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 by
20 # "make mostlyclean". See automake bug#10697.
21 # This is the non-libtool case. Keep this test in sync with sister test
22 # 'subobj-clean-lt-pr10697.sh', which deals with the libtool case.
