36# __cleanuse is invoked with ${.ALLSRC} as the name of a variable
37# (such as CLEANFILES or CLEANDIRFILES), or possibly a list of
38# variable names.  ${.ALLSRC:@v@${${v}}@} will be the list of
39# files to delete.  (We pass the variable name, e.g. CLEANFILES,
40# instead of the file names, e.g. ${CLEANFILES}, because we don't
41# want make to replace any of the file names with the result of
42# searching .PATH.)

48# or CLEANDIRFILES is not completely empty but contains spaces.
49# This can easily happen when CLEANFILES or CLEANDIRFILES is set
