Won't that break the standalone builds? I mean, EXIT is probably quite
appropriate when you are just building the library itself; it's just not
appropriate in the context of the batch regression testing.

Also, what about a half-hundred of other EXIT's in tools/build/*.jam files?
Some of them definitely seem to fall into the same category as the one we
happened to bump into. We are definitely not in favor of the whole thing
breaking again when a month later somebody checks in a target with
an incompatible property or something like it.

How about if instead of EXIT-ing or ECHO-ing we do something like

report_error unknown dependent target $(main-target) ;

and have 'report_error' decide whether it's appropriate to exit or not,
depending on the context, e.g. by defining it differently for the regression

Does it make sense?
