For what it is worth, essentially all Ada compilers have
something analogous to subsystems, typically called "sublibraries"
or "catalogs" or some such thing. Rational's subsystems do have
more mechanism supporting them. In most other compilers, a sublibrary
is just another directory with perhaps a specially-named file or two
(e.g. "ada.lib"). The net result is pretty much the same -- you can
do configuration management over a subset of the sources of a large
system, and bundle together the sources that make up a conceptual
"library" of some sort (e.g. a graphics library, a database library,
etc.) for easier reuse across projects.
Rational subsystems add some amount of visibility control, which
doesn't seem as useful as it was in Ada 83, given the ability to
use child units in Ada 95.
