Re: libexecdir/datadir used incorrectly

[Alfred M. Szmidt]

     The definition of @samp{datadir} is the same for all packages, so
     you should install your data in a subdirectory thereof.  Most
     packages install their data under
     @file{$(datadir)/package-name/}.

I don't think this is clear, i.e. can one do:

datadir := $(datadir)/package-name

Note the := to just evaluate $(datadir) once.  Which would lead to the
awkward scenario "configure --datadir=FOO" and "make datadir=FOO
install" doing different things (assuming that datadir is defined as
address@hidden@ somewhere else and that this is pulled into the
Makefile).

I personally would rather see a wording as is already used in several
places in the GCS.  Like for sbindir:

,----
| This should normally be @file{/usr/local/sbin}, but write it as
| @file{$(exec_prefix)/sbin}.  (If you are using Autoconf, write it as
| @samp{@@sbindir@@}.)
`----

Which is clear that you shouldn't do:

sbindir = @sbindir@/foo
