Of the variables listed above, four have values that are single file
names, and two have values that are lists of file names. These six
have variants that get just the file's directory name or just the file
name within the directory. The variant variables' names are formed by
names, and two have values that are lists of file names. These six have
variants that get just the file's directory name or just the file name
within the directory. The variant variables' names are formed by
appending @samp{D} or @samp{F}, respectively. These variants are
semi-obsolete in GNU @code{make} since the functions @code{dir} and
@code{notdir} can be used to get an equivalent effect (@pxref{Filename
Functions, , Functions for File Names}). Here is a table of the
variants:@refill
@code{notdir} can be used to get a similar effect (@pxref{Filename
Functions, , Functions for File Names}). Note, however, that the
@samp{F} variants all omit the trailing slash which always appears in
the output of the @code{dir} function. Here is a table of the variants:
