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