It's not surprising: since it is "multiplied" by $(<[2]), it disappears
unless there's a second file product as a result of the link. That's only
the case when an import library is being generated (Win32).

Absolutely... although there is a strange effect from doing this: normally,
variables such as IA32ROOT (which I expect is set by the compiler's
installation procedure), are only available if the directory they name is
already in the user's PATH. The result is that the tool is invoked with an
explicit path precisely when it doesn't need to be. I guess it doesn't hurt,

The former, I think. IA32 refers to an architecture, not a compiler.

Thanks; I think I got it compiling, too, but Intel has some
exception-handling bugs which prevent it from working.

Pay attention to

Aha. We should distribute .tar.gz files as well.

I'm not yet sure what it does in case there are multiple boost
installations. The next revision of the build system is supposed to be able
to handle multiple versions of a tool or library being installed.

Hmm; I think this role is supposed to be played by the Jamfile in
BOOST_ROOT. Were you aiming at something different?

> What is your recommendation to cleanup (intermediate) build results?

Ah, what did you have in mind? The Win32 toolsets such as msvc and
metrowerks which are using command-files do something like that using
TEMPORARY. I know that in general, users would rather have object files
deleted, while programmers want them to hang around for the next build.

Do you mean, a way to detect a release build from C++, or from Jam code?

Absolutely; take a look at $(BOOST_ROOT)/status/Jamfile. I have to integrate
the code for generating HTML and capturing compile logs; Jens and I spent
some time discussing this in Redmond. I am a bit torn as to whether to do
this now or after we get the build system rewrite well-established. After
all, we have Jens' tool which works quite well for the time being, and the
way the build system is currently organized makes Jam relatively slow at
processing the status Jamfile.
