AFAIK it's only explained in features.jam where they are declared..
# Add a user include path (#include "x.h").
path-feature "include" ; # <include>../foo/bar/mumble
# Add a system include path (#include <x.h>).
path-feature sysinclude ; # <sysinclude>/fu/man/chu
Whether the toolset can honor that completely is another story :-)

Ideally everyone should be using <sysinclude>$(BOOST_ROOT)

Do you mean that a <sysinclude>$(BOOST_ROOT) gets done automatically for
all? No. Although there are some toolsets which add the path directly
for some unknown reason. And a <sysinclude>$(BOOST_ROOT) gets added to
all test targets automatically.

That should not be a problem, it is wasteful :-)

That usually only happens when something like COMO_PATH, or a related
var, is not configured.

Those would not explain the absence of the como include and lib paths.

I'll see if I can replicate it with cw-8_3 as that's what I have.
