O.k. As far as I understand build variants are configured using the BUILD environment variable (or the -sBUILD=...) option, correct?

Right.

Until now I know of the variants "debug" and "release". And obviously one can specify some modifiers like "<optimization>speed" or "<runtime-link>static|dynamic>", "<debug-symbols>on" and maybe more. I think it should be very simple to find out which build variants and modifiers are defined because this information must be stored in some of the Jam config files. Correct?

see tools/build/features.jam

Just searched through the boost_1_30_0 directories and found such info in the Toolset jam files, e. g. tools/build/sunpro-tools.jam. Somehow a default set of these modifiers must exist for the case that the user did not specify anyone(?)

The variant specifies the first layer of defaults. Anything not in the variant is taken from the feature's first value. Finally, target requirements may override those values.

O.k. I think, this is an acceptable solution because all the Boost libs might be very useful -- if I only could get them all compiled with Sun's Forte compiler:-(((

Sun has a lot of bugs to fix before that can happen.

Thanks, just subscribed to the jamboost Boost Build mailing list. I'm still very new to the build tool BJam. So first I have to learn more about its functioning before being able to contribute.
