[Boost-build] Multiple compiler and cross-compilation support

Hello,

I'm currently evaluating the usage of Boost.Build for our software
development.  We have a rather intricate set of requirements for
building.  I've looked at Boost.Build, and managed to set up a
hierarchical set of project decriptions that builds a simple executable,
but I've been unable to find a good approach for the following aspects
of building:

 * Cross-Compilation support

    This should be obvious, we need to cross-compile for a number of
embedded platforms. I know that's a feature other people need too,
what's a good way to get started?

 * Mixing different compilers

    We need to compile different libraries using different toolsets, and
link them all together into one executable.  It's not clear to me how
this can be done.

 * Separate build directories

    I might want to compile for different embedded devices, which are
all the same nominal platform (WinCE), but require a different set of
<define>s.  How do I express that, and how do I keep the build results
for different sets of <define>s apart?

It would be nice if somebody could give me a few hints there on how to
approach this.

Regards,
Andreas
