Subject: Re: [Boost-build] allowing targets to fail

Here is a related question:
I'm looking at the "try_compile" example, which seems to use a similar
feature: It runs a configure check ("check_target_builds foo") and
allows it to fail, i.e.
the result is captured in a log file rather than on the console, in
addition to a conditional definition of feature sets.
How is this implemented in the engine, i.e. what is the underlying
target definition (as seen by the engine) and what causes the engine not
to report it as an "updated" or "failed target" on the console ?
Oh, and how does the caching work, i.e. where is that implemented ?
