Revert fixes for [rt.cpan.org #61577]

These changes introduced some test failures on AIX and other platforms,
and rather than dig around for more failing platforms during the RCx
period, we will revert this to reapply later when it is more tested.

This reverts commit 01b71c89216c9f447494638a5d108e13c45c3863.

This reverts commit b6903614db213f07401367249dc84c896eb099b7.

This reverts commit 271d04eee1933df0971f54f7bf9a5ca3575e7e6a.
