Module Name: src Committed By: rillig Date: Mon Mar 15 16:45:30 UTC 2021
Modified Files: src/usr.bin/make: lst.c Log Message: make: fix documentation of Lst_MoveAll In CLEANUP mode, was originally meant to track memory allocations but is useful during debugging as well, initialize the list. There is no distinct constant representing an invalid pointer, otherwise that would have been an even better choice.
