+ # With libtool 1.4, dependencies were output in $dir.libs/$base.lo.d.
+ #
+ # With libtool 1.5 this exception was removed, and libtool now
+ # generates 2 separate objects for the 2 libraries. These two
+ # compilations output dependencies in in $dir.libs/$base.o.d and
+ # in $dir$base.o.d. We have to check for both files, because
+ # one of the two compilations can be disabled. We should prefer
+ # $dir$base.o.d over $dir.libs/$base.o.d because the latter is
+ # automatically cleaned when .libs/ is deleted, while ignoring
+ # the former would cause a distcleancheck panic.
