-# Use the replacement ftw.c if the one in the C library is inadequate or buggy.
-# For now, we always use the code in lib/ because libc doesn't have the FTW_DCH
-# or FTW_DCHP that we need.  Arrange to use lib/ftw.h.  And since that
-# implementation uses tsearch.c/tdestroy, add tsearch.o to the list of
-# objects and arrange to use lib/search.h if necessary.
