For warn-on-use.h, I was just following the precedence set by Bruno during arg-nonnull.h. Beyond that, this is more of Bruno's question why he picked build-aux rather than gllib for the templates to live in, particularly given that our *.in.h templates live in gllib. > I want to enable my users to build clisp modules against an existing > system-wide clisp installation (and install the user-built modules in > their home directory), similar to the way cpan works for perl. > > since the configure files refer to some build-aux files, I have to > install those files when I install clisp. I'm not much of a fan of installing from build-aux; so it seems like you have a use case that deserves some refactoring on the gnulib side of things. But at this point, I'm hoping Bruno can step in and comment. > I want to be able to add build_aux=.... to the $(MAKE) invocation > so that the file arg-nonnull.h & warn-on-use.h are found in the right place. In other words, the factorization allows you to override just $(build_aux) as needed. But it depends on us being able to find a way to populate $(build_aux) with the correct default in the absence of your module setup, and is also only relevant if we can't come up with some better upstream layout in the first place. > thanks!
