a) If they are system libraries found outside your project you can add
them to boost/tools/build/v2/site-config.jam like this:
If they are project specific you can add them to Jamroot.jam at the root
of your project hierarchy the same way.
b) You can use conditionals to add additional sources, include paths or
libraries depending on e.g. the target OS:
# Always compiled
# Conditionally compiled depending on OS
c) You can read env variables like this:
import os ;
echo [ os.environ SOME_VAR ] ;
Not entirely sure how you'd set a define based on that, but it might get
d) Already answered in previous reply
e) This has to be virtually possible to answer 100% but all I can say is
that Boost.Build is very flexible. I'd be surprised if there's something
major it can't do compared to gnu make.
Note: All of this was written from memory. Your mileage might vary.
