OK people, here's a really simple proposal to encourage some
discussion on the classification of things and to make it easier to
test.
Consider the following patch to bsd.subdir.mk. Move directories
containing non-'base' items out of the SUBDIR entry and into
foo_SUBDIR lines _after_ the .include of bsd.subdir.mk. The
gymnastics are necessary to avoid inheriting definitions from higher
up, and mean that these changes can be selectively deployed rather
than requiring a huge sweep over the whole tree.
Note that TEXTPROC and DEVEL are arbitrary; if you can think of better
names or other categories, please suggest. If nobody is in violent,
rational opposition to this, how about I commit it and let the
anti-bloatists free?
See my post to hackers about DWIM on ${${FOO}} - I would prefer to
have the names of the categories in a variable inherited from
somewhere else and then iterate over them using .for, but it looks
like that would be hard work without using the shell.
Patch follows (beware snarf-n-barf damage)
