Should probably start here:
http://www.boost.org/doc/libs/1_37_0/libs/test/doc/html/utf/user-guide/usage-variants/static-lib-variant.html

I don't think so. There was some confusion about dynamic library 
variant, but the static library was there from the beginning and never 
really changed much.

Reasonable.

Why? Didn't it work for you out of the box?

This is a bit fishy. This place is only related to the dynamic library 
variant. Though maybe Boost.Build builds both with single command and 
it's fine in that case.

Works fine for me. I just tried and reproduce your exercise.

Maybe clean build would help? Also try to see on results from 
preprocessor: check if init_unit_test is there.
